w a tree diagram to find the number of possible outcomes. Glenn has 4 pants and 3 shirts. How many different pairs of pants and can he wear?

To solve the problem of how many different pairs of pants and shirts Glenn can wear, we can use a tree diagram approach. However, since I can't draw a tree diagram here, I'll explain the process step by step. 1. **Identify the known conditions:** - Glenn has 4 pairs of pants. - Glenn has 3 shirts. 2. **Understanding the combinations:** - For each pair of pants, Glenn can choose any of the shirts. This means that for each pair of pants, there are multiple choices of shirts. 3. **Calculating the total combinations:** - The total number of combinations can be calculated by multiplying the number of pants by the number of shirts. \[ \text{Total combinations} = \text{Number of pants} \times \text{Number of shirts} \] Substituting the known values: \[ \text{Total combinations} = 4 \times 3 \] 4. **Perform the calculation:** \[ \text{Total combinations} = 12 \] Thus, Glenn can wear a total of 12 different pairs of pants and shirts.
