Question

The Texas Department of Transportation (TXDOT) is interested in studying the occurrence of defective paving along a length of highway after a recent resurfacing project. The TXDOT team in charge of the project learn that defects occur at the average rate of two per mile on this type of resurfacing project, and obey the assumptions of a Poisson distribution.

Find the probability of no (i.e., zero) defects in a particular 3-mile section of the highway. Hint: You'll need to calculate the mean defect rate per 3-mile length, λ, using the fact that μ = 2.

Answer 1

thank you.
