Question 581917: For the daily lottery game in a lottery, players select three numbers between 0 and 9. A number cannot be selected more than once, so a winning ticket could be, 203 or 302. 222, or 330 is not allowed. Purchasing one ticket allows you to select one set of numbers. How many different outcomes (three digit numbers) are possible?

If zero at first place is allowed then, total outcomes = 10*9*8 = 720

otherwise, total outcomes = 9 * 9 * 8 = 648
