1) You have a sample of 9 flowers from pea plants.
(a) Suppose 7 of them are white, and 2 of them are purple. If you line them up in a row, how many different arrangements can you get? Note: WWWWWWWPP is one arrangement, WPWPWWWWW is another arrangement, and so on. You do NOT want to actually list all possible arrangements - instead, use what you learned in class to calculate this.
(b) Now suppose 2 of them are white and 7 of them are purple. How many different arrangements can you get?
(c) How many arrangements do you have for 1 white and 8 purple? (d) How many arrangements do you have for 0 white and 9 purple?
