Ответ:
The required probability is 0.04411
Step-by-step explanation:
The number of female grey mice = 5.
The number of males grey mice = 4.
The number of female white mice = 2.
The number of male white mice = 6.
The number of mice = 17.
The probability of first mice be male grey =![\frac{4}{17}](/tpl/images/0528/8353/f4bc6.png)
The probability of second mice be male grey =![\frac{3}{16}](/tpl/images/0528/8353/41c4a.png)
The probability of two mice be male grey =
= 0.04411
