Extracted text: Page く 4 > of 9 Page 4 of 9 The completion of a construction job may be delayed because of a strike. The probabilities are 0.60 that there will be a strike, 0.85 that the construction job will be completed on time if there is no strike, and 0.35 that the construction job will be completed on time if there is a strike. Suppose that we discover later that the job was completed on time. What is the probability that there had been a strike?
