Question 926823
5 children: 3G, 2B
2 chosen ...
P(both boys are selected) = {{{(2/5)(1/4)}}} = 2/20 = 1/10
..........
reasonable for the girls to cry foul and claim that the selection process must not have been random ?
Albeit unlikely, it is possible selection process was at random 
( two boys could be randomly selected 1 out of 10 times)
