I need it solved in Matlab Code Only

Buses arrive to a bus stop according to an exponential distribution with rte of = 4 a. If you arrived at 8:00am to the bus stop, what is the probability that the next b. If you arrived at 8:00am to the bus stop, what is the probability that the next c. If you arrived at 8:00am to the bus stop, what is the probability that the next 1. busses per hour. bus will arrive within an hour? bus will arrive between 9:00 am and 10:00am? bus will arrive after 10:00am?
