A component fails on the average of once every 4 years with 75% of the failures observed to occur during stormy weather. If there are 12 hours of stormy weather to every 240 hours of good weather, what are the failure rates for stormy and good weather, respectively ?
A. λ(Stormy) = 3.939 failure/yr, λ(Good) = 0.0656 failure/yr.
B. λ(Stormy) = 4.202 failure/yr, λ(Good) = 0.0525 failure/yr.
C. λ(Stormy) = 6.594 failure/yr, λ(Good) = 0.0458 failure/yr.
D. λ(Stormy) = 20.16 failure/yr, λ(Good) = 0.0403 failure/yr.
