Question

Брошены две игральные кости. найти вероятность того, что сумма очков на выпавших гранях делится на 7

Answer 1

всего благоприятных исходов 6:

1 6

2 5

3 4

4 3

5 2

6 1

всего исходов 6*6=36 следовательно

6/36=1/6 примерно 16,6% 

Answer 2

Calculating the Probability of the Sum of Dice Divisible by 7

When two dice are thrown, the total number of possible outcomes is 36 (6 faces on the first die multiplied by 6 faces on the second die). To find the probability that the sum of the numbers on the dice is divisible by 7, we need to calculate the number of favorable outcomes and then divide it by the total number of outcomes.

The favorable outcomes are the combinations of numbers on the dice that result in a sum divisible by 7.

The probability can be calculated using the formula: Probability (P) = Number of favorable outcomes / Total number of outcomes

From the search results, we can see that the probability of the sum of the numbers on the dice being divisible by 7 is 1/6 or approximately 0.167 This means that out of the 36 possible outcomes, 6 of them result in a sum divisible by 7.

Conclusion

Therefore, the probability of the sum of the numbers on two dice being divisible by 7 is 1/6 or approximately 0.167.
