Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

Total number of balls = 7 + 12 + 4 = 23

White balls = 12

P(3 white) = (12/23)(11/22)(10/21) = 20/161

Answer: The probability of 3 whites is 20/161
