Homework Help: statistics

Posted by tmac357A on Friday, June 20, 2008 at 8:16pm.

I'm having trouble with estimating probability:

In a study of 685 cars in a parking lot, there were only 3 different types: sedan, sports car and mini-van. 211 of the cars were mini-vans. Use this information to estimate the probability of choosing a car that is a sedan or sports car.

I figure n=685 but after that I'm stuck!

Any help would be great! Thanks!
