Average number of machines

A job shop consists of three machines and two repairmen. The amount of time a machine works before breaking down is exponentially distributed with mean 10. If the amount of time it takes a single repairman to fix a machine is exponentially distributed with mean 8, then

a) what is the average number of machines not in use?

b) what proportion of time are both repairmen busy?
