                            Ms. Smith puts a variety of wrapped chocolate candies into a bag.  There are 5 silver-wrapped candies, 1 purple-wrapped candy, 2 stripped candies and 4 gold-wrapped candies.  If 15 students select one candy at a time out of the bag without looking, and replace the candy after each draw, how many students would be expected to select a gold-wrapped candy from the bag?
                            What is 5 students?
