Question

The time to failure in hours of a system has the density function given as
f(t) =0.002 exp[ 0.0021]
Find the probability that the system will fail in
a) Less than 100 hours
b) Less than 1.000 hours
a 0.18172. 0.8647
b. 0.18172. 0.8764
c. 0.18127. 0.8764
d 0.18127. 0.8647​

Answer 1

Answer:

The (probability that exactly ONE of the failures occurs) is equal to (the probability that the transmission fails and brakes work) plus (the probability that transmission works and brakes fail). Say there are 100 such cars. Of these, 60 have transmissions that will fail, 30 will have brakes that will fail.
