Question 466748
Combinations are when order doesnt matter, permutations are when order does matter.  So the number of ways of selecting 3 people is when order does not matter, because they will still be the same people. so its 8P3 on the graphing calculator which equals 336.  The number of ways of arranging these selected three people is a combination, because order does matter, therefore its 8C3 which equals 56
