Alyssa found a bag of gemstones. There are 2 white ones, 4 green ones, 3 yellow ones, and 5 red ones. She pulled out 2 green stones, 3 red stones, and 1 white stone. Compare the relative frequency of picking a stone that is not red or green to the known probability of selecting a stone that is not red or green. Enter your response as a fraction.(2 points)

The relative frequency of picking a stone that is not red or green is 3/10, since Alyssa picked 1 white stone out of 2 total stones that were not red or green.

The known probability of selecting a stone that is not red or green can be calculated by adding the probabilities of picking white or yellow stones, which is (2+3)/(2+4+3+5) = 5/14.

Therefore, the relative frequency of picking a stone that is not red or green is 3/10, and the known probability is 5/14.
