This is known as the frequentest approach and works well for problems involving discrete amounts. Assume you have a single U. S. Quarter (one of the old ones with President Washington on one side and the American Bald Eagle on the other side). Leave your answer as a fraction a/b. Assuming that you flip your quarter 3 times (with each flip being independent of the others), what is the probability of getting the 1st flip is tail, the 2nd flip is head, and the 3rd flip is tail? Leave your answer as a fraction a/b. You may want to draw a picture to solve this?
