Mr. Sullivan places tiles numbered 1 through 18 in a bag and assigns a number to represent each of the 18 students in his class. Students will present their final reports in the order that their assigned tiles are drawn from the bag. Is Mr. Sullivan being fair?

Question

A.
Mr. Sullivan is being unfair because one tile has equal probability of being selected over another tile.

B.
Mr. Sullivan is being unfair because one tile has higher probability of being selected over another tile.

C.
Mr. Sullivan is being fair because one tile has equal probability of being selected over another tile.

D.
Mr. Sullivan is being fair because one tile has higher probability of being selected over another tile.

Answer 1

A. Mr. Sullivan is being unfair because one tile has equal probability of being selected over another tile.

Since each tile represents a different student, all students should have an equal chance of presenting their final reports first or last. However, if one tile has a higher probability of being selected over another, then Mr. Sullivan's method of drawing tiles is unfair.
