Problema Solution

Mr. And mrs. Worid wants 5 children. What is the probability of having at least one boy?

Answer provided by our tutors

The probability of having one boy a time is P = 0.5

So the probability of having at least one boy =

1- P(none boy)

 = 1- (0.5)^0.5 = 0.96875

So the probability of having at least one boy is 0.96875.
