2.33 M&M Colors. Observing that the proportion of blue M&Ms in his bowl of candy appeared to be less than that of the other colors, R. Fricker, Jr., decided to compare the color distribution in randomly chosen bags of M&Ms to the theoretical distribution reported by M&M/MARS consumer affairs. Fricker published his findings in the article “The Mysterious Case of the Blue M&Ms” (Chance, Vol. 9(4), pp. 19–22). For his study, Fricker bought three bags of M&Ms from local stores and counted the number of each color. The average number of each color in the three bags was distributed as shown in the following table.
Color | Frequency |
Brown | 152 |
Yellow | 114 |
Red | 106 |
Orange | 51 |
Green | 43 |
Blue | 43 |
