Help solving this please! Notes to consider: For part 1, A podium with (1st: horse A; 2nd: horse B; 3rd: horse C) is different than a podium with (1st: horse B; 2nd: horse C; 3rd: horse A). We're asking how many ways the 1st 2nd and 3rd horses could be. Let H = {h_0, h_1, ... h_11} be the 12 horses in the race. Here are two example ways the "podium" can be arranged: (h_3, h_7, h_2), (h_9, h_0, h_11) For part 2, Assume that horses may not share a placement (i.e. they can't "tie").
