Math statistics question

For two events E and F, P(E) = 0.42, P(F) = 0.81, and P(E n F) = 0.30.
Find P(F | E). Round your answer to three decimal places.
a. 0.370
b. 0.714
c. 0.930
d. 0.519
e. None of the above

The conditional probability of event E given event F , written P (E | F ), is

P (E | F ) =P (E ∩ F ) /P(F)
, where P (F ) ≠ 0.

P (E | F ) =0.30/.81
=0.370
option A
