Asked by Aaron

Ok please help me. Here is my stats question

Suppose there is a 20% chance of striking oil at a certain location. An oil company drills at 5 different spots. What is the probablity of them striking oil on at least one of the spots?

Any help is greatly appreciated

The probability of not hitting oil is .8
The probability of not hitting oil in 5 tries is .8^5 = .32768. Ergo, the probability of getting at least 1 hit is (1-.32768) = .67232
