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.
