Full Transcript

We have four players and each are assigned a distinct number from 1 to 50 inclusive, chosen uniformly at random. The player with the lowest number and the player with the highest number form one team, while the two remaining players form the other team. So, the score of a team is the sum of the numbers of its two players. The team with the higher score wins and receives an amount of money equal to the difference between the two team scores from the losing team. The red player is allowed to choose his number before the other numbers are assigned. Which number should the red player choose to maximize the expected winnings of his team?
