5. In a certain animal species, the probability that a healthy adult
female will have no offspring in a given year is .21, while the
Probabilities of 1,2,3, or 4 offspring are respectively, .18, .29, .17,
and .15. If a random variable X is used to represent the number of
offspring, find its mean, variance, and standard deviation.
