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 1 1 310 Start Fraction 3 over 10 End Fraction 710 Start Fraction 7 over 10 End Fraction 37
The complement of not picking a pink marble would be picking a non-pink marble.
So, the total number of non-pink marbles in the bag is: 5 (red) + 8 (green) + 2 (blue) + 6 (white) = 21
The total number of marbles in the bag is: 9 (pink) + 5 (red) + 8 (green) + 2 (blue) + 6 (white) = 30
Therefore, the probability of not picking a pink marble would be the total number of non-pink marbles divided by the total number of marbles: 21/30.
The complement of not picking a pink marble would be picking a pink marble, so the probability of picking a pink marble would be 1 - (21/30) = 9/30 = 3/10.
So, the answer is: Start Fraction 3 over 10 End Fraction.
