Bipin is playing in a game show. The host tells Bipin that there are 10 balls hidden in a box - 5 are Red, 3 are Yellow and 2 are Blue. Bipin pulls out his first ball. It's Red and he wins a large sum of money. Now his choices are:

1. He can stop playing and take his prize.
2. He can pull out another ball - if it's Red he doubles his money, if it's Yellow he leaves with nothing, if it's Blue he can pick one last ball.

What should Bipin do? Why?
