Help on Algebra 2 question! :/?

Asked by kittykat219 (136points) September 10th, 2011

Right my teacher assigned me some homework for the weekend and one of the questions I don’t understand at all! :/ Can you help me figure it out?

If you guess the answers at random, what is the probability of getting at least three correct answers on a five-question true-or-false quiz?

Thanks for your help! :)
