Probability
A local firm recently purchased a stamping machine (newer model) to be used alongside its current stamping machine (old). Only one machine is required to operate at a time. The old machine breakdowns have been recorded in some instances, and the newer machine will be utilized in these situations. Records showed that 8% of the manufacturing time that the old machine had broken down, the newer machine had been successfully used (assume that this probability is valid today). The historical record indicated that the probability that both stamping machines are in good working conditions at the same time is 0.9. Determine the probability that the wo machines will break down when a particular stamping operation is required.
