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.
