Question

The probability of a new washing machine working perfectly is 0.972

what is the probability that your new washer is faulty

Answer 1

0.028

Explanation:

The equation for opposite probabilities is 1 - P(A)

This means 1 minus the probability of event A which in this question is the event of the washing machine working properly.

So to find the chance that it will not work properly:

1 - 0.972 =0.028

I hope this helped!
