Use the appropriate probability model (Poisson).
-For quality control purposes, a company that manufactures copper sheets routinely
Takes samples from its production process. Since its product is often used for decorative
Purposes, one inspection check involves counting the number of imperfections or flaws

Of this size is 3. What is the probability that a sheet of this size has no more than 2
Imperfections?
A) 0.4232
B) 0.2510
C) 0.2240
D) 0.5689
E) 0.0034

Quizplus · Accepted Answer

The probability of having no more than 2 imperfections can be calculated using the Poisson probability formula for 0, 1, and 2 imperfections, with λ = 3. The sum of these probabilities gives approximately 0.4232.
