1) A certain couple is equally likely to have either a boy child or a girl child. If the family has three children, let X denote the number of girls. (10-points) a) Identify the possible values of the random variable X. b) Determine the probability distribution of X c) Use random variable notation to represent the event that the couple has at most 2 girls AND also determine that probability

A young couple decides to keep having children until they have a girl. Assuming a boy or a girl are equi-probable possibilities in the birth of every child and the gender of every child is independent of the previous, what would be the expected number of children the couple would have when the first girl is born? What is the probability that the fourth child would be the first girl?
A couple is planning on having 5 children and the probability of having a girl is...
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.
