Two Basic Rules of Probability · Exercise 27

The following table of data obtained from www.baseball-almanac.com shows hit information for four players. Suppose that one hit from the table is randomly selected.


Are "the hit being made by Hank Aaron" and "the hit being a double" independent events?

(a) Yes, because P(hit by Hank Aaronhit is a double) = P(hit by Hank Aaron)
(b) No, because P(hit by Hank Aaronhit is a double) ≠ P(hit is a double)
(c) No, because P(hit is by Hank Aaronhit is a double) ≠ P(hit by Hank Aaron)
(d) Yes, because P(hit is by Hank Aaronhit is a double) = P(hit is a double)
