I have 4 M&M's (red, yellow, green and brown) in a bag and 1 dime in my pocket. Draw a tree diagram to show the possible outcomes if I first flip the coin and then pick a M&M from the bag.

How many possible outcomes are there?

How many outcomes have a red M&M involved? What is the probability of having a red M&M in the end? What is the probability of having Heads in the end? What is the probability of having a brown M&M and tails in the end?
