The Two Child Probability Problem
Difficulty Level

Mr. Jones has two children. The elder child is a girl. What is the probability that both children are girls?

View Answer Comments(1)

There are 4 possible combinations for the case of 2 children (GG,GB,BG,BB)
Out of 4, Only 2 are favourable combinations in which the elder child is a girl (GG and GB)


So the probability that the younger child is also a girl is 1/2.
