A couple is planning on having 5 children and the probability of having a girl is 0.517. If we define the random variable to be the number of girls in 5 births, then the probability the couple will have less than 3 girls is 0.468.
Is the event the couple will have less than 3 girls an unusual event? Briefly explain.
