Question 1131221: A history pop quiz has one question in which students are asked to arrange the following presidents in chronological order: Hayes, Taft, Polk, Taylor, Grant, and Pierce.
After carefully reading the scenario, determine the number of possible different arrangements of the presidents. Which will work better to determine this answer, permutation or combination? Make an argument as to why your way works.
There are 6 ways to choose the first name. Then, for each of those 6 ways, there are 5 ways to choose the second name, for a total of 30 ways to choose the first two names, then times 4, then times 3... But this is just the formula for the number of PERMUTATIONS of 6 things, namely 6 factorial.
