tree diagram question

Peter has decided to roll a die and toss a coin.
a) Make a tree diagram or use listing / exhaustion to show the possible outcomes.
b) How many different outcomes are there?

Start with flipping a heads. From there, you can roll a 1, 2, 3, 4, 5, or 6. That’s 6 outcomes with heads.

Start with flipping a tails. From there, you can roll a 1, 2, 3, 4, 5, or 6. That’s 6 outcomes with tails.

There are 6 + 6 = 12 outcomes.
