Question

A company makes electronic components for TV's. 90% pass final inspection (and 10% fail and need to be fixed). 200 components are inspected in one day. What is the expected number that fail in one day?

Answer 1

To calculate the expected number of components that fail inspection in one day, you can use the concept of expected value.

First, calculate the number of components expected to pass inspection:

90% of 200 components pass inspection, which is 0.9 * 200 = 180 components.
Now, calculate the number of components expected to fail inspection:

10% of 200 components fail inspection, which is 0.1 * 200 = 20 components.
So, the expected number of components that fail in one day is 20.
