If Sally gave a survey with five colors listed and ask each person who takes the survey to pick one color. She assumes that the results if given to 24 persons the results would be 1/2 blue, 1/12 red, 1/8 blue, 1/4 green, and 1/24 orange. What number of surveys would best prove her assumtion 120 or 240 explain why

240 is better because you get a result that is closer to the true probability of each color when you take a larger number of samples.
