Q17,p3,j14. Assume that a program will experience 200 failures in infinite time. It has now experienced 100 failures. The initial failure intensity was 20 failures/CPU hr. Then the current failure intensity will be

(A) 5 failures/CPU hr

(B) 10 failures/CPU hr.

(C) 20 failures/CPU hr.

(D) 40 failures/CPU hr.

Answer B.

Failure rate is  frequency    for  which an system or component fail. failures per hour. It is often denoted by the  λ(lambda). Mean time between failure is measured by 1/ λ.
