Question 1183255: A machine part may be selected from any of three manufacturers with probabilities p1 = 0.25, p2 = 0.5, p3 = 0.25. The probabilities that it will function properly during a specified period of time are 0.2, 0.3, and 0.4, respectively, for the three manufacturers. Determine the probability that a randomly chosen machine part will function properly for the specified time period
