A particular airline has 10 a.m. flights from Chicago to New York, Atlanta, and Los Angeles. Let A denote the event that the New York flight is full and define events B and C analogously for the other two flights. Suppose P(A) = .9, P(B) = .7, P(C) = .8 and the three events are independent. What is the probability that
a. All three flights are full? That at least one flight is not full?
b. Only the New York flight is full? That exactly one of the three flights is full?
