suppose the probability that a construction company will be awarded a certain contract is .25, the probability that it will be awarded a second contract is .21, and the probability that it will get both contracts is .13. What is the probability that the company will win at least one of the two contracts.
----------------
P(at least one) = 1 - P(none)
----------------
P(get at least one of the two contracts) = 1 - (0.75)((0.79) = 0.4075
