The green jar haves 13 chocolate chip, 10 sugar and 14 peanut butter cookies. The pink jar haves 7 chocolate chip, 5 sugar and 8 peanut butter cookies. One of three cookie jars is selected at random. The probabilities that blue jar, green jar, or pink jar will be selected are 1/2, 1/4, and 1/4 respectively. A cookie is then selected at random from the selected jar. What is the probability that the pink jar was selected, if it is known that the cookie was a sugar cookie?
