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
A. 10 per CPU hr.
B. 0.1 per CPU hr.
C. –0.1 per CPU hr.
D. 90 per CPU hr.
Answer:C
