Solution :
1/3 and 1/2 >>>>>>
Since there are two juveniles in Mr.Sharma's family, at least one of which is a boy, there are three equally probable cases: Boy-Boy, Boy-Girl or Girl-Boy. In only one case, both juveniles are boys, so the probability that both are boys is 1/3.
Mr.Verma's family situation is different. Knowing that the older juvenile is a girl, there are only two equally probable cases:
Girl-Girl or Girl-Boy. Therefore the probability that both juveniles are girls is 1/2 .
