# Joint Probability: Let P(A) = .3, P(B) = .4 and P( A U B ) = .7 a. What is the joint probability of A and B? b. Find the probability of the complement of A.

How would I go about answering these questions? Also, how do you differentiate between solving them as a dependent or an independent event? Let P(A) = .3, P(B) = .4 and P( A ∪ B...
