Answer 1

A uniform probability model describes a situation where every possible outcome has an equal chance of occurring.

Let's analyze the options:

A. Drawing a red or black card from a deck of cards - Not uniform, as there are 26 red and 26 black cards, making them equally likely.

B. Selecting a ball from 2 red balls and 3 yellow balls - Not uniform, as the probabilities are different (2 red and 3 yellow).

C. Selecting a sock from 5 black socks and 10 white socks - Not uniform, as there are different probabilities for each color.

D. Equally divided five-section spinner with three colors - This is uniform if each section has an equal size and each color is equally probable.

The best description of a uniform probability model is **D**, assuming the spinner sections are equal.
