Problem 98E
The manufacturing of semiconductor chips produces 2% defective chips. Assume that the chips are independent and that a lot contains 1000 chips. Approximate the following probabilities:
(a) More than 25 chips are defective.
(b) Between 20 and 30 chips are defective.
ANSWER:
Solution:
Step 1 of 4:
The percentage of defective chips produced in the manufacturing of semiconductor is 2%
The chips are independent.
A lot contains 1000 chips.
We have to find the following probabilities.
- More than 25 chips are defective.
- Between 20 and 30 chips are defective.
