Best ResponseYou've already chosen the best response.0Well, for the first number, there would be 20 number choices. For the second, there would be 19. For the third there would be 18. You get the pattern, right?

Best ResponseYou've already chosen the best response.2uh, not quite, there are only 6 numbers on the ticket following jf04's logic, we see that first number > 20 choices second number > 19 choices, etc. we stop when we get to the sixth number, giving us: 20*19*18*17*16*15 so our probability is 1/(20*19*18*17*16*15)
