Which set of these best describes dependent events?

Question

Tossing a coin and spinning a spinner.
Rolling a number cube and spinning a spinner.
Selecting a marble from a jar of marbles, replacing it, then selecting another marble
Selecting a marble from a jar, not replacing it, then selecting another

Answer 1

The set that best describes dependent events is: selecting a marble from a jar, not replacing it, then selecting another. This is because the outcome of the second selection depends on the result of the first selection, since there is one less marble in the jar to choose from.
