Question 847004: A general contractor has submitted two bids for two projects; A and B. The probability of getting project A is 0.60. The probability of getting project B is 0.60. The probability of getting at least one of the projects is 0.825. If the contractor gets project B, what is the probability that he will get project A

Hi,

P(A OR B) = P(A) + P(B) - P(A∩B)

 .825 = .60 + .60 - P(A∩B)

P(A∩B) = 1.20 - .825 = .375

P(A|B) = P(A and B)/P(B)
