For this problem, use the data from my last posted question.If we consider only the people who named a rainbow color (red, orange, yellow, green, blue, or purple), what percentage of those people preferred red?
Red = 13%
Orange = 4%
Yellow = 5%
Green = 15%
Blue = 16%
Purple = 12%
So......
(13) / (13 + 4 + 5 + 15 + 16 + 12) = 1/5 = 20%
+1310
