Jeannie set out to see if people would resist eating a familiar food in a different color. A popular cafeteria style restaurant allowed her to place rice of 3 different and unusual colors as choices in the selecting/serving line. The colors were purple, green, and blue.

She kept track of how many people choose each type of rice for 1 day. The total number of people selecting rice of any color was 88.
