   3/15 = 1/5 just the number of red balls over the total number of balls.

   This takes me back to middle school……..there is 15 balls….3 are red…the probability is always stated in percent form or ratio…..so 20% or 1:5……….

   The answer is 1 of 3 because they are asking what is the probability of selecting 1 red ball from only 3 red balls that you know are in the bag.
