Computing Competing Probabilities


Solutions

  1. The team with initial possession has over a 60% chance of winning.
  2. For an 11-point game, under a "winner-takes-out" rule, the probability that the team with initial possession wins is 61.5%.
  3. "Loser-takes-out" reduces the first player's advantage to 58.6%.
  4. Adding in a four point shot makes the odds for the first player to win an 11-point game to 57.7% in the "loser-takes-out" scenario.
  5. Having an inside shot be worth 1 and an outside shot point worth 2 makes the 11 point game longer so the initial team has only a 56% chance of winning.
