The number of visible defects on a product container is thought to be Poisson distributed with a mean equal to 3.5. Based on this, the probability that 2 containers will contain a total of less than 2 defects is:
A) 0.0223
B) 0.1359
C) 0.0073
D) 0.1850

Question

Quizplus · Accepted Answer

The total number of defects in 2 containers is Poisson distributed with a mean equal to 7 (3.5 per container times 2). The probability of less than 2 defects is found using the Poisson probability formula, which for this scenario gives a value close to the option C (0.0073).
