To find the actual probability of each color you do: color /total P(pink) = 15/75 = .20 P(green) = 22/75 = .29 P(red) = 19/75 = .25 P(yellow) = 19/75 = .25 If you've calculated correctly the probabilities should add to 1 (or very close because of rounding!) I know this is little more than the question asked but it's important for the concept. The gumball with the greatest probability of being picked is a green gumball.
