 # --description--
 
-Although not required for `label` elements with a nested `input`, it is still best-practice to explicitly link a `label` with its corresponding `input` element.
+`input` 要素がネストされている `label` 要素の場合は必須ではないものの、`label` は対応する `input` 要素と明示的に関連付けることがベストプラクティスです。
 
-Now, add a `for` attribute to each of your four `label`s that links the `label` to its corresponding radio `input`.
+4 つの `label` 要素にそれぞれ `for` 属性を追加して、`label` を 対応するラジオボタンの `input` 要素に関連付けてください。
 
 # --hints--
 
-You should give the first `label` a `for` attribute.
+1 つ目の `label` に `for` 属性を追加してください。
 
 ```js
 assert.notEmpty(document.querySelectorAll('ul.answers-list > li > label')?.[0]?.htmlFor);
 ```
 
-You should give the first `label` a `for` attribute matching the `id` of its `input` element.
+1 つ目の `label` に、対応する `input` 要素の `id` と一致する `for` 属性を設定してください。
 
 ```js
 const htmlFor = document.querySelectorAll('ul.answers-list > li > label')?.[0]?.htmlFor;
 assert.equal(htmlFor, document.querySelectorAll('ul.answers-list > li > label > input')?.[0]?.id);
 ```
 
-You should give the second `label` a `for` attribute.

-Next, add a `min` attribute to the `input` with a value of `13` because users under the age of 13 should not register. Also, users probably will not be over the age of 120; add a `max` attribute with a value of `120`.
+次に、13 歳未満のユーザーが登録できないように、`input` に `min` 属性を追加して値を `13` に設定してください。 また、120 歳より年上のユーザーが登録することはおそらくないでしょう。`max` 属性を追加して、値を `120` に設定してください。
 
 これで、範囲外の値でフォームを送信しようとすると警告が表示され、フォームが送信されないようになりました。 試してみてください。

-Most browsers inject their own default CSS properties and values for different elements. If you look closely, you might be able to notice the file `input` is smaller than the other text `input` elements. By default, a `padding` of `1px 2px` is given to `input` elements you can type in.
+多くのブラウザーは、さまざまな要素に対して独自にデフォルトの CSS プロパティと値を挿入します。 注意して見ると、ファイルの `input` 要素が他のテキストの `input` 要素よりも小さいことが分かるかもしれません。 文字を入力できる `input` 要素の `padding` は、デフォルトで `1px 2px` に設定されています。
 
-Using another attribute selector, style the `input` with a `type` of `file` to be the same padding as the other `input` elements.
+属性セレクターをもう 1 つ使用して、`type` が `file` の `input` 要素のパディングを、他の `input` 要素と同じにしてください。

+`@media` アットルールはメディアクエリとも呼ばれ、条件付きで CSS を適用する場合に使用します。 メディアクエリはよく、`max-width` および `min-width` プロパティを使用して、ビューポートの幅に基づいて CSS を適用するために使われます。
 
-In the below example the padding is applied to the `.card` class when the viewport is `960px` wide and below.

 ## Правила
 
-The function will return the correct conversion if the supplied problems are properly formatted, otherwise, it will **return** a **string** that describes an error that is meaningful to the user.
+Функція поверне правильне перетворення, якщо надані приклади відформатовані правильно. В іншому випадку буде **повернений** **рядок**, який описує помилку, важливу для користувача.
 
 
-- Situations that will return an error:
-  - If there are **too many problems** supplied to the function. The limit is **five**, anything more will return: `Error: Too many problems.`
-  - The appropriate operators the function will accept are **addition** and **subtraction**. Multiplication and division will return an error. Other operators not mentioned in this bullet point will not need to be tested. The error returned will be: `Error: Operator must be '+' or '-'.`
-  - Each number (operand) should only contain digits. Otherwise, the function will return: `Error: Numbers must only contain digits.`
-  - Each operand (aka number on each side of the operator) has a max of four digits in width. Otherwise, the error string returned will be: `Error: Numbers cannot be more than four digits.`
-- If the user supplied the correct format of problems, the conversion you return will follow these rules:
-  - There should be a single space between the operator and the longest of the two operands, the operator will be on the same line as the second operand, both operands will be in the same order as provided (the first will be the top one and the second will be the bottom).
-  - Numbers should be right-aligned.
-  - There should be four spaces between each problem.
-  - There should be dashes at the bottom of each problem. The dashes should run along the entire length of each problem individually. (The example above shows what this should look like.)
+- Ситуації, які повернуть помилку:
+  - Функції надано **забагато прикладів**. Ліміт складає **5 прикладів**. Якщо їх більше, то повернеться `Error: Too many problems.`
+  - Функція приймає відповідні оператори: **додавання** та **віднімання**. Множення та ділення поверне помилку. Інші оператори, які не згадані тут, тестовані не будуть. Повернеться помилка `Error: Operator must be '+' or '-'.`
+  - Кожне число (операнд) повинне містити лише цифри. В іншому випадку функція поверне `Error: Numbers must only contain digits.`
+  - Кожен операнд (тобто число з кожної сторони оператора) може мати максимум чотири цифри по ширині. В іншому випадку помилковий рядок видасть `Error: Numbers cannot be more than four digits.`
+- Якщо користувач надав правильний формат прикладу, то перетворення буде слідувати наступним правилам:
+  - Повинен бути лише один пробіл між оператором і найдовшим із двох операндів, оператор буде на тому ж рядку, що й другий операнд, обоє операндів будуть в однаковому порядку, як і надано (перший буде зверху, а другий буде знизу).
+  - Числа повинні бути вирівняні за правим краєм.
+  - Між кожним прикладом повинно бути чотири пробіли.
+  - Знизу кожного прикладу повинна бути риска. Риска повинна йти по всій довжині прикладу індивідуально. (На прикладі вище видно, як це повинно виглядати.)

-A hat will always be created with at least one ball. The arguments passed into the hat object upon creation should be converted to a `contents` instance variable. `contents` should be a list of strings containing one item for each ball in the hat. Each item in the list should be a color name representing a single ball of that color. For example, if your hat is `{"red": 2, "blue": 1}`, `contents` should be `["red", "red", "blue"]`.
+Капелюх завжди створюється з принаймні однією кулькою. Аргументи, які передаються в об'єкт-капелюх, під час створення мають конвертуватися в поле класу `contents`. `contents` має бути списком рядків, де один елемент дорівнює кожній кульці у капелюсі. Кожний елемент списку має бути назвою кольору, яка позначає кульку певного кольору. Наприклад, якщо ваш капелюх `{"red": 2, "blue": 1}`, то `contents` має бути `["red", "red", "blue"]`.
 
-The `Hat` class should have a `draw` method that accepts an argument indicating the number of balls to draw from the hat. This method should remove balls at random from `contents` and return those balls as a list of strings. The balls should not go back into the hat during the draw, similar to an urn experiment without replacement. If the number of balls to draw exceeds the available quantity, return all the balls.
+Клас `Hat` повинен мати метод `draw`, який приймає аргумент з позначенням кількості кульок, які можна витягти з капелюха. Цей метод має випадково витягати кульки з `contents` та повертати ці кульки списком рядків. Кульки не повинні повертатися до капелюха після того, як їх витягли (як в експерименті з урною без заміни). Якщо кількість кульок, яку треба витягти, перевищує доступну кількість, поверніть усі кульки.
 
-Next, create an `experiment` function in `prob_calculator.py` (not inside the `Hat` class). Ця функція повинна приймати наступні аргументи:
+Потім створіть функцію `experiment` в `prob_calculator.py` (не в класі `Hat`). Ця функція повинна приймати наступні аргументи:
 
-- `hat`: A hat object containing balls that should be copied inside the function.
-- `expected_balls`: An object indicating the exact group of balls to attempt to draw from the hat for the experiment. For example, to determine the probability of drawing 2 blue balls and 1 red ball from the hat, set `expected_balls` to `{"blue":2, "red":1}`.
-- `num_balls_drawn`: The number of balls to draw out of the hat in each experiment.
-- `num_experiments`: The number of experiments to perform. (The more experiments performed, the more accurate the approximate probability will be.)
+- `hat`: об'єкт-капелюх з кульками, який має бути скопійований у функцію.
+- `expected_balls`: об'єкт, який вказує на точну кількість кульок, котру треба вийняти з капелюха для експерименту. Наприклад, щоб визначити вірогідність того, що ви витягнете 2 сині та 1 червону кульки з капелюха, встановіть `expected_balls` на `{"blue":2, "red":1}`.
+- `num_balls_drawn`: кількість кульок, які треба витягти з капелюха в кожному експерименті.
+- `num_experiments`: кількість експериментів, які треба провести. (Чим більше експериментів було проведено, тим точнішою буде вірогідність.)
 
-The `experiment` function should return a probability.
+Функція `experiment` повинна повертати вірогідність.
 
-For example, if you want to determine the probability of getting at least two red balls and one green ball when you draw five balls from a hat containing six black, four red, and three green. To do this, you will perform `N` experiments, count how many times `M` you get at least two red balls and one green ball, and estimate the probability as `M/N`. Each experiment consists of starting with a hat containing the specified balls, drawing several balls, and checking if you got the balls you were attempting to draw.
+Допустимо, якщо ви хочете визначити вірогідність витягти щонайменше 2 червоні кульки та одну зелену, коли витягаєте п'ять кульок з капелюха, де лежить шість чорних, чотири червоні та три зелені кульки. Для цього вам треба виконати `N` експериментів, порахувати скільки `M` разів ви можете витягти принаймні дві червоні кульки та одну зелену кульку та вирахувати вірогідність як `M/N`. Кожен експеримент складається з капелюха (з певними кульками), витягування декількох кульок та перевірки, чи ви витягли необхідні кульки.
 
-Here is how you would call the `experiment` function based on the example above with 2000 experiments:
+Ось так ви можете викликати функцію `experiment`, базуючись на прикладі зверху з 2000 експериментами:

-Since this is based on random draws, the probability will be slightly different each time the code is run.
+Оскільки все базується на випадкових витяганнях, то вірогідність буде злегка відрізнятися з кожним новим запуском коду.
