A woman plans to bear three children. The probability of having a boy is 50%. Out of the three childer she bears, determine:
a) Mean number of boys (using the formula) (Ans: 1.5)
b) Standard Deviation of the number of boys (using the formula) (Ans: 0.866)
c) Sketch the density function of the number of boys and comment on whether the mean and standard deviation in parts a and b are plausible. (Ans: P={0.125 0.375 0.375 0.125} for 0, 1, 2, and 3 respectively)
d) Sketch the distribution function of the number of boys.

There were 2,074,000 baby girl and 2,173,000 baby boy born. We often assume that theprobability of having a boy or a girl is 0.5 because of the chromosomal determination of sex inhumans. Is there reason to think that the sex ratio in the United States favor more baby boys?To answer this question, find the probability that an equal chance of getting a boy would give2,173,000 boys or more in 4,247,000. What do you conclude?
