A certain type of artificial heart has four independent, critical components.Failure of any one of these components is a serious problem that will cause the artificial heart to fail. The 5 year failure rate for each component follows: component 1=.02, component 2=.05, component 3=.04, component 4=.03.

What is the probability that an artificial heart functions for 5 years?

I first solved for what is probability each component wont fail (1-probability will fail). Then multiply all probabilities that wont fail

1 answer

Either-or probabilities are found by adding the individual probabilities.

Do that for failure rates, then subtract from 1.
