Answer 4

It's just P(Woman|Liked the restaurant) or the probability that you choose a woman given that they liked the restaurant

Answer 5

The correct answer was .56 but I don't know how?

Answer 6

aww probability
\[P(A |B) = \frac{P(AB)}{P(B)}\]
P(AB) is probability of person being woman AND liking restaurant....36/100 meet that criteria
P(B) is prob of liking restaurant (45+36)/100 meet that criteria
\[P(A|B) = \frac{.36}{.81}\]

Answer 7

answer is 0.56 ?
that would be true if question was
P(Man | like restaurant)

Answer 8

That's so weird, maybe the question was wrong. Cause I got 36/81 which is .44. Thanks though.

Answer 9
