Question

In a family having three children, there may be no girl, one girl, two girls or three girls. So, the probability of each is `1/4`. Is this correct? Justify your answer

Answer 1

No it is not correct that in a family having three children, there may be no girl, one girl, two girls or three girls, the probability of each is `1/4`.

Let boys be B and girls be G

Outcomes can be BBB, GGG, BBG, BGB, GBB, GGB, GBG, BGG

Then Probability of 3 girls = `1/8`

Probability of 0 girls = `1/8`

Probability of 2 girls = `3/8`

Probability of 1 girl = `3/8`
