Hint: For parts (a) and (b) below, using the definition of conditional probability and the fact of independence of
R and D, we can know that: P(M₁, Rj|Dk) = P(Mi|Dk, Rj)P(Rj).
(a) Compute P(M, R|D₁) for all possible values of M and R; that is, find:
• P(Mo, R₂|D₁)
• P(Mo, R3|D1)
• P(M₁, R₂|D1)
• P(M₁, R3|D1)
(b) Compute P(M, R|Do) for all possible values of M and R; that is, find:
• P(Mo, R₂|Do)
• P(Mo, R3|Do)
• P(M₁, R₂|Do)
• P(M₁, R3|Do)
(c) Using part (a), give the distribution of points earned given a shot is defended and compute the expected
value of points earned when a shot is defended.
(d) Using part (b), give the distribution of points earned given a shot is not defended and compute the expected
value of points earned when a shot is not defended.
(e) Using parts (c) and (d), compute the difference in expected points earned between defended and unde-
fended shots. Write one sentence, easily understood by a non-technical reader, which explains what this difference
represents.

(6) At the top of the next page is a Bayes Net graph and four tables which characterize how four random variables
interact to describe a single basketball shot:
• D (defended): whether the player taking the shot was defended (D₁) or not (Do) while taking the shot.
● R (range): whether the player took a 2-point shot (R₂) or a 3-point shot (R3).
● M (made): whether the shot was made (M₁) or not (Mo).
● P (points): the points earned as a result of the shot, either 0 (Po), 2 (P₂), or 3 (P3).
