Mobile telephones perform handoffs as they move from cell to cell. During a call, a telephone either performs zero handoffs (H0), one handoff (H1), or more than one handoff (H2). In addition, each call is either long (L), if it lasts more than three minutes, or brief (B). The following table describes the probabilities of the possible types of calls.

What is the probability P[H0] that a phone makes no handoffs? What is the probability a call is brief? What is the probability a call is long or there are at least two handoffs?
