Our faucet is broken, and a plumber has been called. the arrival time of the plumber is uniformly distributed between 1pm and 7pm. the time required to fix the broken faucet is then exponentially distributed with mean 30 minutes.
supposing that the two times are independent, find the expected value and the variance of the time at which the plumber completes the project.

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
