A construction firm bids on two different contracts. Let El be the event that the bid on the first
contract is successful, and define E2 analogously for the second contract. Suppose that P(El) =
0.38 and P(E2) = 0.18 and that El and E2 are independent events
a. Calculate the probability that both bids are successful (the probability of the event El and E2).
b. Calculate the probability that neither bid is successful (the probability of the event (not El)
and (not E2)).
c. What is the probability that the firm is successful in at least one of the two bids?
