# Probability Basics

Not what you're looking for?

I'm trying to calculate these probabilities given the top row as reference to go off of. I can figure out the first one as it 1- it's compliment. I don't need the answers, I just would like to know how each is calculated to find the answers. There has to be a basic formula for this? Thanks!

P(A) = 0.1, P(B|A) = 0.39, P(B?A ? )=0.39

P(A-bar) = 1- 0.25 = 0.75

P(B-bar|A) =

P(B-bar|A-bar)=

P(B)=1-P(B-bar)=

P(B-bar)=1-P(B)

P(A|B)=

P(A-bar)|B)=

P(A|B-bar)=

P(A-bar|B-bar)=
