Answer

Answer:

  1. First, calculate the expected - value for the 2 - point shot:
    • The probability of making the 2 - point shot is (P_2 = 0.8). If they make the 2 - point shot, the game goes to overtime. In overtime, assume the probability of winning is (0.5). So the probability of making the 2 - point shot and then winning in overtime is (0.8\times0.5 = 0.4). If they miss the 2 - point shot (with probability (1 - 0.8=0.2)), they lose. The expected value of the 2 - point shot for winning the game is (E_2=0.8\times0.5+0.2\times0 = 0.4).
  2. Then, calculate the expected - value for the 3 - point shot:
    • The probability of making the 3 - point shot is (P_3 = 0.4), and if they make it, they win. If they miss (with probability (1 - 0.4 = 0.6)), they lose. The expected value of the 3 - point shot for winning the game is (E_3=0.4\times1+0.6\times0 = 0.4).

So the answer is: They are equally likely to win.
