To determine Find the probability that malfunction came from station C when a malfunction was reported and it was found to be caused by other human errors. Explanation Calculation: Probability: Let A be the event , then the probability of event A is, P ( A ) = n N Where, n : Number of outcomes correspond to event A N : Total number of outcomes Bayes’ Rule: Let B 1 , B 2 , ... , B k constitute a partition of the sample space S such that P ( B i ) ≠ 0 for i = 1 , 2 , … , k , then for any event A of S such that P ( A ) ≠ 0 , P ( B r | A ) = P ( B r ) P ( A | B r ) ∑ i = 1 k P ( B i ) P ( A | B i ) for r = 1 , 2 , … , k . Let event A is defined as that the station A , event B is defined as that the station B , event C is defined as that the station C , and event E is defined that a malfunction by other human errors. The totals for the all stations is, Station A B C Total Problems with electricity supplied 2 1 1 4 Computer malfunction 4 3 2 9 Malfunctioning electrical equipment 5 4 2 11 Caused by other human errors 7 7 5 19 Total 18 15 10 43 The probability of selecting station A is, P ( A ) = 18 43 The probability of selecting station B is, P ( B )</
