What is the probability of having 16 years of education? What is the probability of having 20 years of education? (b) What is the probability of earning \$ 30,000 conditional on having 12 years of education? (c) What is the probability of earning \$ 60,000 conditional on having 16 years of education? What is the probability of earning \$ 90,000 conditional on having 16 years of education? (d) Compare you answers to (b) and (c). Does it increase you earnings to obtain 16 years of education instead of 12? (e) What is the covariance between years of education and income?
