A computer center has three printers A, B, and C which print at different speeds. Programs are routed to the first available printer. The probability that a program is routed to printers A, B, and C are .6, .3, and .1 respectively. Occasionally a printer will jam and destroy a printout. The probability that printers A, B, and C will jam are .01, .05, and .04 respectively. Your program is destroyed when a printer jams. What is the probability that printer A is involved? printer B is involved? printer C is involved?
