What is the probability for a family with three children to have a boy and two girls (assuming the probability of having a boy or a girl is equal)?
a) 1/8
b) ¼
c) ½
d) 3/8
e) 5/8
I did tend to go this way :-
as only possibilities are 3G, 3B, 2G & 1B, 2B & 1G,
hence, 1/4, without going through 1/2 for boy and girl types...
I know this approach is very wrong, please help me in clearing such a basic doubt
