Marvin wants to buy a new rifle. He saw just the one he wanted advertised in the newspaper at a very low price. When he went to buy the gun, the store salesperson told Marvin the sale gun was out of stock and inferior. The salesperson then proceeded to convince Marvin to buy a rifle that cost much more money than he had intended to spend. Marvin likely has been victimized by .

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
