Dan's Diner employs three dishwashers. Al washes 20 %20% of the dishes and breaks only 1 %1% of those he handles. Betty and Chuck each wash 40 %40% of the dishes, and Betty breaks only 1 %1% of hers, but Chuck breaks 3 %3% of the dishes he washes. You go to Dan's for supper one night and hear a dish break at the sink. What's the probability that Chuck is on the job?
