A manufacturer of MP3 players purchases major electronic components as modules. The

reliabilities of components differ by supplier (see below diagram). Suppose that the

configuration of the major components is given by:

The components that can be purchased from three different suppliers. The reliabilities of

the components are as follows:

Component Supplier 1 Supplier 2 Supplier 3

A .97 .92 .95

B .85 .90 .90

C . .95 .93 .88

Transportation and purchasing considerations require that only one supplier be chosen.

Which one should be selected if the MP3 player is to have the highest possible reliability?
