Q. The failure intensity for a basic model as a function of failures experienced is given as λ(μ)-λ0[1 – (μ)/(V0)] where λ0 is the initial failure intensity at the start of the execution, μ is the average or expected number of failures at a given point in time, the quantity V0 is the total number of failures that would occur in infinite time.
Assume that a program will experience 100 failures in infinite time, the initial failure intensity was 10 failures/CPU hr. Then the decrement of failures intensity per failure will be
