6. When local calls are made in NYC, 55% go through on the first try, and the rest get a busy signal. (We assume there is no third possibility). Let X=# times a call is actually placed for the call to go through On each try, the call goes through with probability .55, and different tries are independent. a. Identify the distribution of X-name and parameter(s). Explain your choice. What is P[X>1]. b. How many calls do you expect to have to place in order to get through 5 times? First identify the distribution of the # of calls required to get through 5 different times. c. Let X=total # of calls that get a busy line when 10 different numbers are attempted, once each. i. What is the distribution of X ; values and probabilities. ii. What is P[ X >2]
