B.(50x49x48)/(5,000³)
C.(99/100)³

Weegy: The answer is B.720 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ It all depends on how precise you want to be:
Technically, there are:
10*9*8 = 720 non-repeating three digit numbers
Why? Because every time a digit is used, [ it is removed from the choices available for the other two digits.
