Question

In a manufacturing industry, out of 500 ma- chine parts checked, 25 are found to be faulty. If a part is bought by a customer from the 500 parts, what is the probability that it will not be a faulty one?​

Answer 1

`A` - a part is not faulty

`|\Omega|=500\\|A|=500-25=475\\\\P(A)=(475)/(500)=(19)/(20)=95\%`
