Emma has a bag of marbles.There are 9 pink 5 red 8 green 2 blue and 6 white marbles in the back.Calculate the compliment of not picking a pink marble
The probability of not picking a pink marble is the same as picking a marble that is not pink.
So, the compliment of not picking a pink marble is picking a pink marble.
The total number of marbles in the bag is:
9 (pink) + 5 (red) + 8 (green) + 2 (blue) + 6 (white) = 30 marbles
The probability of picking a pink marble is:
9 (pink marbles) / 30 (total marbles) = 3/10
Therefore, the compliment of not picking a pink marble is 1 - 3/10 = 7/10 or 70%.
