The complement of not picking a pink marble would be the probability of picking a marble that is not pink.
Total marbles = 9 + 5 + 8 + 2 + 6 = 30
Number of pink marbles = 9
Number of marbles that are not pink = 30 - 9 = 21

Therefore, the complement of not picking a pink marble is 21/30 = 7/10 = 0.7.

The correct answer is 710.
