im has 30 jellybeans, with equal numbers of three flavors—raspberry, pineapple, and orange. He likes raspberry the best. So far, Tim has eaten 6 orange and 4 pineapple jellybeans. What are the chances that the next one he picks will be raspberry?
If he has 30 jellybeans, he most likely has 10 of each flavor. If he eats 6 orange and 4 pineapple, he would have 20 jellybeans left. There would still be 10 raspberry, so it would be a 10/20 probability :)
