I feel this is not answering the question correctly. Either all boy or all girl. It answers all girls and not a boy.prateek_guy2004 wrote:This is a easy approach.....[email protected] wrote:The probability of having a girl in all 3 cases is :

The probability of NOT having a boy in all 3 cases is :
=> 1/2*1/2*1/2= 1/8
Therefore the probability of having a girl and not a boy will be;
=> 1/8 +1/8
=> 2/8
=> 1/4
Ans : 1/4
Somebody clarify.
