<PRE><B>Question 1048646</B>
probability(P) that the contractor wins a contract = 0.25 = 1/4
:
probability(P) that the contractor does not win a contract = 1 - 0.25 = 3/4
:
a) P (winning both contracts ) = (1/4) * (1/4) = 1/16
:
b) P ( does not win a contract ) = (3/4) * (3/4) = 9/16
:
c) P ( wins one contract ) = (1/4) * (3/4) = 3/16
