50. Each participant in a certain study was assigned a sequence of 3 different letters from the set {A, B, C, D, E, F, G, H}. If no sequence was assigned to more than one participant and if 36 of the possible sequences were not assigned, what was the number of participants in the study? (Note, for example, that the sequence A, B, C is different from the sequence C, B, A.)

I disagree with the OA!! help ??

Answer is 300

total number of possibilities : 8*7*6=48*7=336
36 of the possible sequences were not assigned so we are left with 336-36=300 possibilities
