If 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.
