To determine which spinner represents a uniform probability model, we need to find the spinner in which all outcomes have an equal chance of occurring.
Here is the breakdown:
- **Spinner a**: White is the largest choice, while red and blue are equal and smaller. (Non-uniform)
- **Spinner b**: Blue is the largest choice, red is the smallest, and white is in between. (Non-uniform)
- **Spinner c**: All choices are equal (red, blue, and white). (Uniform)
- **Spinner d**: Blue is the largest, while red and white are equal and smaller. (Non-uniform)
**Conclusion**: The spinner that represents a uniform probability model is **c. spinner c** because all colors (red, blue, and white) have equal probability.

For the second part, we need to identify the situation that represents a non-uniform probability model:
- **a. rolling a 2 on a six-sided die**: This is uniform, as each number has a 1/6 chance.
- **b. landing on heads from a flip of a coin**: This is also uniform, as both heads and tails have a 1/2 chance.
- **c. spinning yellow on a spinner with 4 equal parts**: This is uniform since each part has an equal probability.
- **d. drawing a red ball from a bag containing 5 red and 3 blue balls**: This is non-uniform because the probability of drawing a red ball (5/8) is greater than that of drawing a blue ball (3/8).
**Conclusion**: The situation that represents an event from a non-uniform probability model is **d. drawing a red ball from a bag that contains 5 red balls and 3 blue balls**.
Here is the breakdown:
- **Spinner a**: White is the largest choice, while red and blue are equal and smaller. (Non-uniform)
- **Spinner b**: Blue is the largest choice, red is the smallest, and white is in between. (Non-uniform)
- **Spinner c**: All choices are equal (red, blue, and white). (Uniform)
- **Spinner d**: Blue is the largest, while red and white are equal and smaller. (Non-uniform)
**Conclusion**: The spinner that represents a uniform probability model is **c. spinner c** because all colors (red, blue, and white) have equal probability.
