Answer:    1/22

Step-by-step explanation:

Вероятность вытащить оба белых шара есть умножение вероятностей 2-х событий:

Р(белый,белый)=Р(первым выберут белый шар)*Р(вторым выберут белый шар)

Р(первым выберут белый шар)=3/12=1/4

Но после того как выбрали белый шар , остались только 2 белых шара и всего осталось 11 шаров.  Поэтому

Р(вторым выберут белый шар)= 2/11

Р(белый,белый)=1/4*2/11=2/44=1/22
