Question

Four numbers are drawn from random tiles numbereed 0 through 9. What are the odds of drawing numbers 1 through four in any order?

Answer 1

so you want 1-2-3-4

prob = (1/10)(1/9)(1/8)(1/7) = 1/5040

prob of not getting 1-2-3-4 is 5039/5040

so the odds in favour of 1-2-3-4 is (1/5040) / (5039/5040)
= 1 : 5039
