    Here's a hint my old teacher taught me. Permutations- PICK (they both start with P) Combination- Choose (they both start with C) ...Is this your quiz??

    Re-arranging the letters in a word is thought of as a Permutation because order matters. When I am choosing 5 players to start a basketball game from a team of 13, order doesn't matter. I just need to choose 5 out of a group of 13 so this is a Combination.

    With a word like algebra, you are thinking of the number of ways you can order 7 letters divided by the number of ways each ordering will appear (here is where you divide out by 2 for the repeated a's).
