Hello, shilz222!

An airline has 3 flights from Chicago to NY, Atlanta, and LA.

Let denote the event that the New York flight is full

and define events and analogously.

And: .

and the three events are independent.

Compute the following probabilities:

(a) (i) all 3 flights are full. (ii) at least one flight is not full.

. . . . Yes!

. . . . Right!

(b) (i) only the New York flight is full. (ii) exactly one of the three flights is full.
