2. Команда состоит из двух стрелков. Числа очков, выбиваемых каждым из них при одном выстреле, являются случайными величинами Х1 и Х2 , которые характеризуются следующими законами распределения:
Число очков Х1 3 4 5
Вероятность 0,2 0,3 0,5

Число очков Х2 1 2 3 4 5
Вероятность 0,1 0,1 0,1 0,2 0,5
Результаты стрельбы одного стрелка не влияют на результаты стрельбы второго. Составить закон распределения числа очков, выбиваемых данной командой, если стрелки сделают по одному выстрелу.
