The number of surface flaws in a plastic roll used

Jason Yuhas 2022-01-17 Answered
The number of surface flaws in a plastic roll used in the interior of automobiles has a Poisson distribution with a mean of 0.06 flaw per square foot of plastic roll. What is the probability that there are no surface flaws in an auto’s interior?

Probability of no surfac flaw in interior of automobile is 0.52(2dp)
Explanation:
If XPo(λ) then P(x=r)=eλλr!r
Let automobile interior contains 11 ft of plastic roll.
λ=0.06 / foot of roll. λ=0.0611=0.66 for 11 ft of plastic roll.
For no surface flaw r=0
P(x=0)=e0.66(λ)0!0=0.516851
Probability of no surface flaw in interior of automobile is 0.52 (2dp)
