Explanation / Answer

probability that given a purchaser is Female, they will buy a Fusion =

P(female) = 21/40 = 0.525

P(female and Fusion) = 2/40 = 0.05

probability that given a purchaser is Female, they will buy a Fusion = 0.05/0.525 = 0.095

probability that given someone bought an Escape, they make $79,000 or more

P(Escape)=12/40 = 0.3

P(>79000 and Escape) = 5/40 = 0.125

probability that given someone bought an Escape, they make $79,000 or more = 0.125/0.3 =0.417
