## Homework Statement

Of the items produced daily by a factory, 40% come from line I and 60% from line II. Line I

has a defect rate of 8%, whereas line II has a defect rate of 10%. If an item is chosen at random

from the day’s production, find the probability that it will not be defective.

## Homework Equations

## The Attempt at a Solution

My answer is 0.82 because Line I with no defect is 0.32+Line II with no defect is 0.50.

OR

1-Both lines defected (0.18)=0.82.

Is my approach correct?
