9. Кубик бросают дважды. Какова вероятность того, что первым выпадет число 5, а вторым — четное число:

A) $ \frac{7}{6} $;

B) $ \frac{1}{12} $;

C) $1$ ;

D) $0,75$ ;

E) $0,5$?

Решение 2. №9 (с. 75)

Для решения этой задачи необходимо определить вероятность наступления двух независимых событий. Стандартный игральный кубик имеет 6 граней (1, 2, 3, 4, 5, 6).

1. Найдем вероятность первого события: "при первом броске выпадет число 5".

На кубике только одна грань с числом 5. Всего возможных исходов при одном броске — 6. Вероятность этого события ($P_1$) рассчитывается как отношение числа благоприятных исходов к общему числу исходов:

$P_1 = \frac{1}{6}$

2. Найдем вероятность второго события: "при втором броске выпадет четное число".

Четными числами на кубике являются 2, 4 и 6. То есть, у нас есть 3 благоприятных исхода. Общее число исходов также равно 6. Вероятность этого события ($P_2$) равна:

$P_2 = \frac{3}{6} = \frac{1}{2}$

3. Рассчитаем итоговую вероятность.

Поскольку результаты двух бросков не зависят друг от друга, они являются независимыми событиями. Вероятность того, что оба события произойдут, равна произведению их отдельных вероятностей:

$P = P_1 \times P_2 = \frac{1}{6} \times \frac{1}{2} = \frac{1}{12}$

Сравнивая полученный результат с предложенными вариантами, видим, что он соответствует варианту B.

Ответ: B) $\frac{1}{12}$
