Problem: Safety engineers must determine whether industrial workers can operate a machine's emergency shutoff device. Among a group of test subjects, 66% were successful with their left hands, 85% with their right hands, and 51% with both hands.

c) Are success with right and left hands mutually exclusive? Explain.
