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 0.75. The probability of getting at least one of the projects is 0.85. What is the probability that the contractor will get both projects? Round to the nearest 2 places.

P(a and b)=
P(a)+P(b)-P(a or b) =
0.6+0.75-0.85=
0.50
