We are going to name the people A, B, C, and D 1. A, B, C, then D 2. A, B, D, then C 3. A, C, B then D 4. A, C, D, then B 5. A, D, B, then C 6. A, D, C, then B So at this rate, if there is 6 for the first letter, then there will be 6 for the others, so 6 x 4 = 24, so there are 24 different outcomes. Hope this helped!
