A system contains 10 independent failure modes with CFR hazards of the same rates (i.e., ? mode failures per month). If a design life of 5 month with a reliability of 0.92 is required,

a) What should the system MTTF?

b) What is the median time to failure?

c) What is MTTF with respect to each individual failure mode (in the absence of other failure modes)?

PLEASE HELP

Question 2) A system contains 10 independent failure modes with CFR hazards of the same rates {i.e., 1mm, failures per month). If a design life of 5 month with a reliability of 0.92 is required, a) What should the system MI'TF'? b) What is the median time to failure? e) What is MTTF with respect to each individual failure mode (in the absence of other failure modes)
