I am planning on purchasing a new Tractor, There are two machine choices, Tractor A and Tractor B. Tractor A will cost $175,000 and Tractor B will cost $275,000. Due to various uncertainties in manufacturing operations, the useful life of each machine is unknown, but the following probability estimates have been made.

A. Determine the expected life of each machine.
B. Based on the ratio of purchase cost to expected life, which machine would you recommend?
