Answer:
Here's a tree diagram to represent all of the possible outcomes for the coin landing on red or on yellow:
/ Red \
/ \
/ \
Start End
\ /
\ /
\Yellow/
The "Start" node represents the beginning of the experiment, and it has two branches: one for the coin landing on red, and one for the coin landing on yellow. The branches lead to the "Red" and "Yellow" nodes, respectively, which represent the possible outcomes. Finally, each outcome leads to the "End" node, which represents the end of the experiment.
