The answer involves calculating the probability of selecting a non-red button from a bag containing three different colored buttons.
Mathematics: The question involves calculating the probability of drawing a non-red button from a bag containing pink, red, and yellow buttons.
To find the probability of picking a button that is not red, we need to add the probabilities of picking a pink button and a yellow button since these are the non-red buttons in the bag.
The total number of buttons in the bag is 3 pink + 4 red + 6 yellow = 13 buttons. The probability of picking a non-red button is (3 pink + 6 yellow) / 13 = 9 / 13.
