Each number on the die will be paired with each side of the coin.
Your sample space would be:
1H, 1T
2H, 2T
3H, 3T
4H, 4T
5H, 5T
6H, 6T
When you draw it out you would have the number 1 with two "branches" coming off of it. One branch would have an H at the end and the other branch a T.
Do the same for each number to form the tree.
