A quality control engineer tests the quality of produced computers.
------------
Suppose that 5% of computers have defects, and defects occur independently of each other. Find the probability that the engineer has to test at least 5 computers in order to find a defective one.
-----------------
P(1st 4 are without defect) = 0.95^4 = 0.8145
---
P(test at least 5 to find a defective one) = 0.8145
