Well, for each of these 30 scenarios, how many different people could you put in chair number three? Well, you're still gonna have four people standing up, not in chairs. So for each of these 30 scenarios, you have four people who you could put in chair number three. So your total number of scenarios or your total number of permutations, where we care who's sitting in which chair, is six times five times four, which is equal to 120 permutations. Permutations. Now, permutations. Now, it's worth thinking about what permutations are counting.
