Solution

To create a tree diagram for this scenario, you would start with a single point, or "node," which represents the beginning of the experiment. From this node, you would draw six branches, each representing one of the possible outcomes of rolling a cube with faces numbered 1 through 6. At the end of each of these branches, you would then draw two more branches, representing the possible outcomes of flipping a coin (heads or tails).

The tree diagram would look something like this:

Start
|  
|---1
|   |---H
|   |---T
|
|---2
|   |---H
|   |---T
|
|---3
|   |---H
|   |---T
|
|---4
|   |---H
|   |---T
|
|---5
|   |---H
|   |---T
|
|---6
|   |---H
|   |---T

Each path from the start to an end of a branch represents a unique outcome of the experiment. There are 12 possible outcomes in total.

The probability of any single outcome occurring is 1 out of the total number of outcomes. So, the probability of rolling a 5 and the coin landing heads up is 1/12, or approximately 0.0833, or 8.33%.
