solve the following

**Poisson Distribution in Automobile Service Facility**

The number of customers arriving per hour at a certain automobile service facility is assumed to follow a Poisson distribution with a mean \( \lambda = 6 \).

### Questions:

**(a) Compute the probability that more than 10 customers will arrive in a 2-hour period.**

1. **Click here to view page 1 of the table of Poisson probability sums.**
2. **Click here to view page 2 of the table of Poisson probability sums.**
3. **Click here to view page 3 of the table of Poisson probability sums.**

**(b) What is the mean number of arrivals during a 2-hour period?**

Detailed breakdown of linked resources: 
- **Page 1**: This page typically lists the cumulative probabilities for various values of a Poisson-distributed variable, typically sorted in ascending order starting from the smallest possible value of the variable.
- **Page 2**: This page continues the listing of such cumulative probabilities up to a higher range of variable values.
- **Page 3**: This page operates similarly and concludes the listing of cumulative probabilities up to the highest supported range of variable values.

### Answers:

**(a) The probability that more than 10 customers will arrive is \( \) .**  
*(Round to four decimal places as needed.)*

**(b) The mean number of arrivals is \( \) .**  
*(Type an integer or a decimal. Do not round.)*

---

Note: To compute the probability in part (a), you would typically use the cumulative distribution function (CDF) for the Poisson distribution. For part (b), the mean number of arrivals can be directly determined from the given mean \( \lambda \) and the time period considered.
