Question

В случайном эксперименте бросают две игральные кости. Найдите вероятность того, что в сумме выпадет 7 очков. Ответ округлите до двух знаков после запятой.

Answer 1

На первом кубике может выпать 1,2,3,4,5,6 очков.,а на двух кубиках 6*6=36.Записать все варианты чтобы получилось 7:(1:6),(2,5),(5:2),(6:1)(3:4),(4:3)----всего получилось 6=) 6/36=1/6=0,17

Answer 2

Calculating the Probability of Rolling a Sum of 7 with Two Dice

To calculate the probability of rolling a sum of 7 with two dice, we need to determine the number of favorable outcomes (the sum of the dice is 7) and the total number of possible outcomes.

The total number of possible outcomes when rolling two dice is 36 (6 possible outcomes for the first die multiplied by 6 possible outcomes for the second die).

To find the number of favorable outcomes (the sum of the dice is 7), we can list all the possible combinations:

- (1, 6) - (2, 5) - (3, 4) - (4, 3) - (5, 2) - (6, 1)

There are 6 favorable outcomes.

Therefore, the probability of rolling a sum of 7 with two dice is 6/36, which simplifies to 1/6 or approximately 0.17 when rounded to two decimal places.
