Answer
Explanation:
Step1: Analyze probability concept
In a fair - selection process with 18 numbered tiles in a bag, each tile should have an equal chance of being drawn. The probability of drawing any single tile out of 18 tiles is $\frac{1}{18}$ for each tile.
Step2: Evaluate fairness
Since each of the 18 tiles has an equal probability of being selected, Mr. Sullivan's method of determining the order of student presentations is fair.
Answer:
C. Mr. Sullivan is being fair because one tile has equal probability of being selected over another tile.
