You are now the recent parent of a small baby. Congratulations. Said baby now needs frequent diaper changes Assume that the baby needs its diaper changed regularly, though at uncertain times during the day, which are Poisson distributed over time at a rate (a) of approximately 1 diaper(s) change every 0.9 hours. You need groceries and hop into your car with the baby and diaper bag to go to the store. "f a round trip to the store takes 1.6 hours, what is the probability that you will need to change at least one diaper before you get home? number (rtol=D0.01, atol=D0.0001)

Matthew the Barber owns a one-chair shop. At barber college, they told Matthew that his customers would exhibit a Poisson arrival distribution and that he would provide an exponential service distribution. His market survey data indicate that customers arrive at a rate of two per hour. It will take Matthew an average of 20 minutes to give a haircut. Based on these figures, find the following: Part (a): The average number of customers waiting. Part (b): The average time a customer waits. Part (c): The average time a customer is in the shop.
