Question

Выпадение любой грани игральной кости одинаково вероятно. Найдите вероятность того, что выпадет грань с числом очков, делящихся на 3.( Нужно расписать то как решали)

Answer 1

Ответ:

Объяснение:

Вероятность событий = число благоприятных исходов / общее число исходов

или другими словами сказать вариантов

числа делящиеся на 3 это 3 и 6 всего 2 благоприятных исхода

всего чисел 6

Р=2/6=1/3

Answer 2

Calculating the Probability of Rolling a Number Divisible by 3 on a Six-Sided Die

To find the probability of rolling a number divisible by 3 on a six-sided die, we can start by determining the total number of favorable outcomes and then divide it by the total number of possible outcomes.

1. Total Number of Possible Outcomes: - A standard six-sided die has 6 faces, numbered 1 through 6. - Therefore, the total number of possible outcomes is 6.

2. Favorable Outcomes (Numbers Divisible by 3): - The numbers on a six-sided die that are divisible by 3 are 3 and 6.

3. Calculating the Probability: - The probability of an event is calculated as the number of favorable outcomes divided by the total number of possible outcomes. - In this case, the probability of rolling a number divisible by 3 is 2 (favorable outcomes) divided by 6 (total possible outcomes).

- Therefore, the probability is: ``` 2/6 = 1/3 ```

- So, the probability of rolling a number divisible by 3 on a six-sided die is 1/3.

Conclusion

The probability of rolling a number divisible by 3 on a six-sided die is 1/3. This means that if you roll the die many times, you can expect approximately one-third of the rolls to result in a number divisible by 3.
