A computer hardware has a yearly 83% rate of success.?
What is the probability that if you buy four computers, all four computer hardwares will remain successful within a year?

About 10,000 times the probability you will learn ANYTHING in your statistics class if you have to ask Yahoo Answers EVERY question in your homework.

Only slightly more than 83%, and much less than the answer that whoever wrote this question thought was the answer. They're not independent events. Even though probability theory would indicate only a .17^4 chance that they'd all fail, it's actually much more likely, because it could turn out to be badly designed hardware, or they could all be destroyed by a fire or power surge.
The way to get the answer that would be marked correct is simple -- raise .83 to the 4th power.
But that's really the wrong answer in practice.

0.83 * 0.83 * 0.83 * 0.83
