Analysis of historical data shows the probability a machine tool your company produces will fail when installed in a customer’s

Vesna [10]

Answer:

0.9986

Step-by-step explanation:

Prob (Machine tool actually fails) = 0.04
So, Prob (Machine tool actually functions) = 1 - 0.04 = 0.96

Prob (functional machine tool claimed fail) = 0.08
So, Prob (functional machine tool claimed functional) = 1- 0.08 = 0.92

Prob (fail machine tool claimed fail) = 0.97
So, Prob (fail machine tool claimed functional) = 1- 0.97 = 0.03

Prob A: P [Machine tool indicated (claimed) functional] :- Functional machine tool or fail machine tool claimed functional = (0.96)(0.92) + (0.04)(0.03) = 0.8844

Prob B: P [Machine tool actually function when passed by QAs] = (0.96)(0.92) = 0.8832

Prob (A given B) = P (A & B) / P (A)

= 0.8832 / 0.8844 = 0.9986
