Question

Aaron, Bob, and Charlotte are running a race. Which event would be considered dependent?

determining the chance that Bob comes in first or third
determining whose coach runs the stopwatch
determining which person begins on the inside lane
determining first, second, and third place runners

Answer 1

Determining first, second, and third place runners.

Reason: those placements are dependent — once one person occupies a place it changes the possibilities (and probabilities) for the remaining places.
