You can put this solution on YOUR website! 13. (4 pts) At an annual flower show, 6 different entries are to be arranged in a row.
a) How many different arrangements of the entries are possible?
Ans: 6! = 720
------------------------
b) If the owners of the 1st, 2nd, and 3rd place entries will be awarded prizes of $100, $50, and $25 respectively, how many ways can the prizes be awarded?
And: 6C3 = 6!/[6-3)!3!] = 7*6*5/1*2*3 = 35 ways
