Let event F be choosing a person who is a fan of professional football and let event C be choosing a person who is a fan of car racing.
Which statements are true? Check all that apply.

P(F|C) = 0.75
P(C|F) = 0.25
P(C∩F) = 0.09
P(C∩F) = P(F∩C)
P(C|F) = P(F|C)

Answer 2

Answer:

P(F/C) = 0.75

P(C^F) = 0.09

P(C^F) = P(F^C)

Step-by-step explanation:

P(C^F) = 9% = 0.09

P(C^F) = P(F^C)

P(F/C) = P(F^C)/P(C)

= 0.09/0.12 = 0.75
