Statistics

Suppose a machine has two components that prevent injury; component A and component B. If either of the components fail, an employee will be injured. It is important to note that both A and B cannot fail at the same time. (In other words, they are mutually exclusive events.) If the failure rate for component A is 0.0005 and component B is 0.004, what is the probability an employee will be injured because of c?

A. 0.0045 or 4.5 X10^-3

B. 0.000002 or 2 X 10^-6

C. 0.004 or 4 X 10^-3
