conversations.value: I would love to understand how to solve this problem: Robby doesn't like the color brown and will not eat the brown M&M's.  On his first bag, he sets aside  9 brown M&M's.  On the second bag, he sets aside 12.  On his third & fourth bag, there are 8 brown M&M's that he doesn't eat. On his fifth bag, there are only 3 brown M&M's that he doesn't eat.  What's the average number of brown M&M's in a bag?
  Can you explain?

conversations.value: Out of 5 bags, he had 9+12+8+8+3 = 40 brown M&M's
  He ate 5 bags so the average number of brown M&M's per bag was 40/5 = 8 brown M&M's
