Solution Preview

The average number of errors 4.8.
What is the probability that errors will see fewer than 6?
Solution: This is a Poisson experiment in which we know the following:
 μ = 4.8; since 4.8 errors per windshield, on average.
 x = 0, 1, 2, 3, 4, 5
 e = 2.71828; since e is a constant equal to approximately 2.71828.
Thus, ...
