A process that polishes a mirrored surface leaves an average of 2 small flaws per 5 m2
Chapter 4, Problem 12(choose chapter or problem)
A process that polishes a mirrored surface leaves an average of 2 small flaws per \(5 m^{2}\) of surface. The number of flaws on an area of surface follows a Poisson distribution.
a. What is the probability that a surface with area \(3 m \times 5 m\) will contain more than 5 flaws?
b. What is the probability that a surface with area \(2 m \times 3 m\) will contain no flaws?
c. What is the probability that 50 surfaces, each with dimensions \(3 m \times 6 m\), will contain more than 350 flaws in total?
