Question

Probability of atleasr one boy in a family of four children

Answer 1

Hey,

We need two assumptions to answer this:

It is equally likely to have a boy or a girlEach child’s gender is independent of the gender of the older siblings.

With these assumptions, the probability having 4 girls is (1/2)^4=1/16

The complement of the event of having 4 girls is the event of having at least one boy, which has the probability 1–1/16=15/16.

HOPE IT HELPS YOU:-))

Answer 2

It is the probability of at least one boy
