For two events E and F
suppose E given F = 1/2
P(F given E) = 2/5
and P(E given compliment F) = 7/10
What is p(F)?




I know the correct answer is 14/29 but how do you come to that conclusion?


Thanks!

I suggest that you read your textbook/class-notes. This is not a tutorial service.

This one deals with the theorems of "conditional probabilities." Applying those theorems to the three given statements should get you two equations in the two unknowns P(E) and P(F).

Show us your work!
