Question
The text discusses a problem involving the Poisson process in the context of a towing service.

---

The number of requests for assistance received by a towing service is modeled as a Poisson process with a rate of \( \alpha = 4 \) per hour.

**(a)** Compute the probability that exactly eleven requests are received during a particular 5-hour period. (Round your answer to three decimal places.)

*Response:* [Blank space with incorrect response indicator]

**(b)** If the operators of the towing service take a 30-minute break for lunch, what is the probability that they do not miss any calls for assistance? (Round your answer to three decimal places.)

*Response:* 0.135

**(c)** How many calls would you expect during their break?

*Response:* 2

You may need to use the appropriate table in the Appendix of Tables to answer this question.
