B) 3 or 4 customers in 10 minutes

*Show work in excel

Answer #1

We are asked to get the probabilities here in EXCEL. The EXCEL formulas will be used here to compute the required probabilities.

We are given the distribution here as:

a) The probability of no customer in 10 minutes is computed in EXCEL as:

The answer here is 0.0067

**Therefore 0.0067 is the required probability
here.**

b) Similar to the above case, the probability here is computed as:

0.3158 is the sum of P(X = 3) and P(X =4)

**Therefore 0.3158 is the required probability
here.**

Customers arrive at a restaurant according to a Poisson
distribution at a rate of 30 customers per hour. The restaurant
opens for business at 11:00 am. (Assume that customers will stay
long enough). Find the probability of having 20 customers in the
restaurant at 11:12 am given that there were 17 customers at 11:07
am.

B. Customers arrive at a restaurant according to a Poisson
process. On the average, a customer arrives every half hour.
(a) What is the probability that, 1 hour after opening, there at
least one customer has arrived?
(b) What is the probability that at least 2 customers have
arrived?
