For a T- mobile store, monitor customer arrivals at one-minute intervals. Let X be tenth interval with one or more arrivals. The probability of one or more arrivals in a one-minute interval is 0.090. Which of the following should be used? O X Exponential (0.1) O X Binomial (10,0.090) O X Pascal (10,0.090) O X Geomtric (0.090) For a T-mobile store, monitor the arrival of customers for 50 minutes. Let X be the number of customers who arrive in 50 minutes. The expected arrival time of the first customer is 10 minutes. To find the probability P left square bracket X equals 10 right square bracket. Which of the following should be used? O X Poisson (5) O X Pascal (10,0.090) O X Exponential (0.1) O X Binomial(10,0.090)
