B Correct answer
Explanation

The total number of possible outcomes when two people choose a number from 1 to 25 is 25 * 25 = 625. There are 25 outcomes where they choose the same number (1,1; 2,2; etc.). The probability of winning is 25/625 = 1/25. Therefore, the probability of not winning is 1 - 1/25 = 24/25.
