Well 4 out of the 5 are odd. So the probability the first digit is odd is (4/5) since that digit is no longer available, then the probability the second digit is odd is (3/4), then for the third (2/3), then the forth (1/2).

So to find the first four being odd is (4/5)*(3/4)*(2/3)*(1/2) = 24/120 = .20
