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) Responses 3/10 3/7 1 7/10
The complement of not picking a pink marble is picking any marble that is not pink.
Total number of marbles = 9 (pink) + 5 (red) + 8 (green) + 2 (blue) + 6 (white) = 30 marbles
Number of marbles that are not pink = 30 total marbles - 9 pink marbles = 21 marbles
Probability of not picking a pink marble (complement) = Number of marbles that are not pink / Total number of marbles = 21 / 30 = 7/10
Therefore, the correct answer is 7/10.
