1. Monitor a phone call. Classify the call as a voice call (V ) if someone is speaking, or a data call
(D) if the call is carrying a modem or fax signal. Classify the call as long (L) if the call lasts for more
than three minutes; otherwise classify the call as brief (B). Based on data collected by the
telephone company, we use the following probability model: P[V] = 0.7, P[L] = 0.6, P[V L] = 0.35.
Find the following probabilities:
(1) P[DL]
(2) P[D U L]
(3) P[V B]
(4) P[V U L]
(5) P[V U D] (6) P[LB]
