The probability that the contractor will get both projects is 0.52

Project A probability = 0.65

Project B probability = 0.77

Least one of the projects probability = 0.90

Hence:

P(A)=0.65

P(B)=0.77

P(A∪B)=0.90

Using this formula

P(a and b)=P(a)+P(b)-P(a ∪ b)

Let plug in the formula

P(a and b)=0.65+0.77-0.90

P(a and b)=0.52

Inconclusion the probability that the contractor will get both projects is 0.52.
