Question 475325: if a 3-digit number (000 to 999) i chosen at random, find the
probability that exactly 1 digit will be >5. Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! 3 ways of choosing a place,
4 ways of selecting a digit > 5 in the chosen place,
6 ways of filling any one of the 2 remaining places,
6 ways of filling the last place, assuming repetition of digits.
==> 3*4*6*6 = 432
==> probability is .
