colored jelly beans

Q: You have a bucket of jelly beans. Some are red, some are blue, and some green. With your eyes closed, pick out 2 of a like color. How many do you have to grab to be sure you have 2 of the same?
A: since there are three different colors, we need to grab at least 3+1=4 beans to make sure 2 of them are same.
