In both A and B, lives a family with two children each.
The House A has a family with a boy who loves to play football. Their other child likes to swim.

You are asked:

What will your probable answer?
Both houses are equally likely to have girl child.
Answer- House A
Explanation:
In the House A–
As per puzzle, 1 child is Boy
There can be three possibilities.
———————–
Older | Younger
———————–
Boy | Girl
Girl | Boy
Boy | Boy
All these options are equally possible and thus we will take them all into account.
Two of the cases have a girl and thus the probability here will be 2/3.
In the House B-
As per puzzle, the elder child is a boy and thus there can be only two possibilities:
————————–
Older | Younger
————————-
Boy | Girl
Boy | Boy
Here, the probability of having a girl child will be 1/2.
Thus we must select the house A, as there is better probability of having a girl in that house.
