A maintenance firm has gathered the following information regarding the failure mechanisms forair conditioning systems:Evidence of Gas LeaksYesNoEvidence ofYes5517electrical failureNo323The units without evidence of gas leaks or electrical failure showed other types of failure. If thisis a representative sample of AC failure, find the probability: That there is no evidence ofelectrical failure given that there was a gas leak. And that there is no evidence of a gas leak giventhat there is evidence of electrical failure. (Show complete solution in your answer sheet)a. 0.764, 0.632O b.0.632, 0.764O c.
