If we want to calculate the complement of not picking a pink marble, we need to find the probability of picking any other color marble aside from pink.
Total marbles in the bag = 9 (pink) + 5 (red) + 8 (green) + 2 (blue) + 6 (white) = 30 marbles
Probability of not picking a pink marble = Probability of picking a marble that is not pink = 1 - Probability of picking a pink marble = 1 - 9/30 = 21/30 = 7/10
Therefore, the complement of not picking a pink marble is 7/10.
