Question

MTBF ( Mean Time Between -failure) is a measure of reliability for computer based system . If MTTF and MTTR are mean-time- to- failure and mean -time- to -repair respectively, select the correct relationship
1) MTBF = MTTF+MTTR
2) MTTF = MTBF + MTTR
3) MTTR = MTBF + MTTR
4) MTBF = MTTF + MTTR

Answer 1

Explanation:

I' m not sure... But i think it's answer will be MTBF=MTTF+MTTR
