Errors in estimating job costs. a construction company employs three sales engineers. engineers 1,2, and 3 estimated the costs of 30%, 20% and 50%, respectively, of all jobs bid on by the company. for i=1,2,3, define ei to be the event that a job is estimated by engineer i. the following probabilities describe the rates at which engineers make serious errors in estimating costs:
a) if a particular bid results in a serious error in estimating job cost, what is the probability that the error was made by engineer 1?
b) if a particular bid results in a serious error in estimating job cost, what is the probability that the error was made by engineer 2?
c) if a particular bid results in a serious error in estimating job cost, what is the probability that the error was made by engineer 3?
