The printer can print 40 pages per minute, but it has a 5% jamming rate, which means that 5% of the time, the printer will be jammed and unable to print. This means that the printer can effectively print 40 * 0.95 = 38 pages per minute. Additionally, 20% of the time is lost on account of the operator loading the paper, aligning the print cartridge, etc., which means that the printer can effectively print 38 * 0.8 = 30.4 pages per minute.
