(a)

Answer to Problem 60E
Theprobability of both the vehicle being available is
Explanation of Solution
Given:
Theprobability that the special vehicle is available during availability is
Calculation:
Consider the case that the fire company has two fire vehicle such that the probability of vehicle available is
Then, the probability that the vehicle is not available is,
The probability that both the two vehicles are available at the same time is,
Then, the probability that the vehicle is available is,
