Пошаговое объяснение:

При распределении Пуассона, вероятность того, что будет ровно k вызовов будет находиться по формуле:

P(k) = 1/k! * a^k * e^{-a},

Где а - параметр, равный математическому ожиданию, то есть среднему числу вызовов (в нашем случае а=6), е - экспонента. Подставляем значения в формулу и получаем:

Р(5) = 1/5! * 6^5 * е^-6 = 0,16
