Calculate the probability that a repair will require $30$ or fewer minutes $(0\mathrm{.}5$ hours$)$ to complete.

Place your calculation in cell$$E$6.$

Use the EXPON.DIST function.

Reference the lambda $($C$2)$ in your formula.

Note that the service time is expressed in hours.

Place your calculation in cell$$C$5.$

Use the EXPON.DIST function.$$

Reference the required service time $($B$5)$ and lambda of $0\mathrm{.}75($C$2)$ in your formula.$$

Reuse your formula to calculate the individual probabilities of the other required service times in

Use the POISSON.DIST function.

Reference the average number of customers needing service per day $($C$2)$ in your formula.

Use the POISSON.DIST function.

Reference the number of customers in cell$$B$5$and the average number of customers needing service per day $($C$2)$ in your formula.

Reuse your formula to calculate the individual probabilities of the numbers of customers needing service in range$$B$5$:B$34$on a given day.
