Как сравнить наблюдаемые и ожидаемые события?

Предположим, у меня есть одна выборка частот из 4 возможных событий: Event1 - 5 E2 - 1 E3 - 0 E4 - 12 и у меня есть ожидаемые вероятности того, что мои события произойдут: p1 - 0.2 p2 - 0.1 p3 - 0.1 p4 - 0.6 С суммой наблюдаемых частот моих четырех событий (18) я могу рассчитать ожидаемые частоты...
