There are a total of 5 possible outcomes for the number of tires sold (0, 1, 2, 3, or 4). Therefore, each outcome has a probability of 1/5 or 0.2. On the 1-100 scale, this is equivalent to a range of 20 (100/5) for each outcome.

For the outcome of selling 2 tires, this would fall into the range of 41-60 (2 x 20 + 1-20 for the lower end) on the 1-100 scale. Therefore, C) 41 through 60 is the best choice.
