A couple decided to have 5 children.

(a) What is the probability that they will have at least two girls?

(b) What is the probability that all the children will be of the same gender?

So base on the said question where as ask to calculate the probability of the said problem, and base on the given in the question, the answers are the following.

A. the probability that they will have at least two girls would be 25/32

B. the probability that all the children will be of the same gender would be 2/32 or 1/16.

A) 2/5 = 40%

B) (1/2) ^5 = 1/32 there is two types of genders so the possibilities are 2/32 = 1/16
