Emma has a bag of marbles. There are 9 pink, 5 red, 8 green, 2 blue, and 6 white marbles in the bag. Calculate the complement of not picking a pink marble.(1 point)
The complement of not picking a pink marble is picking any marble that is not pink.
Total number of marbles in the bag = 9 pink + 5 red + 8 green + 2 blue + 6 white = 30 marbles
Probability of not picking a pink marble = (total number of non-pink marbles) / (total number of marbles)
= (5 red + 8 green + 2 blue + 6 white) / 30
= 21 / 30
= 0.7
Therefore, the complement of not picking a pink marble is 0.7.
