A local company that provides home repair services

for appliances has two repairmen who make all of

the home repairs. The company sends Repairman D

on 70% of all jobs because the likelihood of him getting

a second follow-up call within a week is only

0.08, whereas the probability of Repairman K getting

a second follow-up call within a week is 0.20.

If you recently had a repair job done at your home

and it requires a second follow-up call, what is the

probability that Repairman K did your initial repair

work?
