**MathMate**, Wednesday, June 6, 2012 at 10:33pmIf 200<n<300, then the first digit must be 2. That leaves 4 digits for each of the remaining digits for a total of m=1*4*4*4 numbers.

If there is no limitation, the number of all possible (distinct) numbers is

N=4^4.

The probability that a number formed by the digits 1,2,3,4 will fall into that range is therefore m/N.
