Answer 1

gud ques !! can u give some more hint!!

Answer 2

this is all of the problem I was given. sorry

Answer 3

I think it is about probability
in each birth, there is 1/2 chance to get a boy.
There is two children and each birth has one child.
Therefore, (1/2)+(1/2) = 1 boy
Is this right?

Answer 4

It is a probabilty question...
