Question

A textile manufacturer reports an average of 0.02 defects per meter of fabric. For a roll that is 100 meters long, (a) determine the appropriate lambda for modeling defects on the whole roll, and (b) compute the probability that the roll contains at least one defect.

Accepted Answer

Lambda = 2; P(at least one defect) ≈ 0.86466 (≈ 86.47%)

Answer

Lambda = 2; P(at least one defect) ≈ 0.13533 (≈ 13.53%)

Answer

Lambda = 200; P(at least one defect) ≈ 1.0

Answer

Lambda = 0.02; P(at least one defect) ≈ 0.0198
