1. In Example 15.6-1, do the following:

*

(a) Compute Lq directly using the formula 2:::c+l(n - c)Pn.

(b) Compute Ws from Lq.

*

(c) Compute the average number of cars that will not be able to enter the parking lot during an 8-hour period.

*

(d) Show that c - (Ls - Lq ), the average number of empty spaces, equals

~c-I

.LJn=O(c - n)Pn'
