e, incoming calls 30% A particular telephone number is used to receive both voice calls and fax messages. Suppose that 35% of the incoming calls involve fax messages, and consider a sample of 30 incoming calls. What is the probability that: 3. a. 6 of the calls involve a fax message. b. At least 5 of the calls involve a fax message.
