C,
5 choices for unit digit, left 9 for tens digit and 8 for hundreds digit (the suquence of tens hundreds does not matter), makes 5*9*8=360
Exceptions are those having 0 at both tens and hundreds digit: 1, 3, 5, 7, 9. Thus 360+5=365
Actually, I forgot those exceptions at first.....fortunately there is not an option of 360....lol |
