A biologist is studying an endangered species of lemur and hasfound that for some reason on average 80% of the offspring at birthare females and 20% of the offspring are males. Suppose a zooanticipates that it's captive lemurs will produce 30 offspring.

A. What is the expected number of females in this batch ofoffspring?

B. What is the probability that no males will be born?


C. What is the probability that no females will be born?

D. What is the probability that exactly 5 males will beborn? Use the binomial expansion.
