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)
