You are playing a carnival game with a partner. Your partner is blindfolded and you are given two buckets and four marbles (2 red marbles and 2 blue marbles). You get to place the marbles in any way that you would like into the buckets. Then your partner will choose a bucket and then, from that bucket, choose a marble. You win if your partner chooses a red marble. How should you put the marbles in the buckets to maximize your chance of winning?
