Ответ:

1/32

Пошаговое объяснение:

Вероятности независимых событий домножаются, а т.к. вероятность выпадении решки в первый, второй, третий, четвертый, пятый раз никак не зависят друг от друга, это именно наш случай.

Есть два равновероятных исхода, либо выпала решка, либо орел. Из этих случаев нам подходит только один, поэтому вероятность, что выпала решка равна 1/2.

А вероятность, что решка выпала 5 раз подряд = (1/2)*(1/2)*(1/2)*(1/2)*(1/2)=(1/32)
