In E 4.139

a. Construct a joint probability distribution.
b. Determine the probability distribution of weight for rookies; that is, construct a table showing the conditional probabilities that a rookie weighs under 200 pounds, between 200 and 300 pounds, and over 300 pounds.
c. Determine the probability distribution of years of experience for players who weigh under 200 pounds.
d. The probability distributions in parts (b) and (c) are examples of a conditional probability distribution. Determine two other conditional probability distributions for the data on weight and years of experience for the New England Patriots.
