A dependent event is when the outcome of one event affects the outcome of another event.
In the options provided, the scenario that represents a dependent event is:
"determining the reward for completing chores from a spinner that contains 6 different rewards and omitting the selected reward from the list once it has been selected."
In this case, once a reward is selected, it is removed from the available options, which means the next spin's outcome is dependent on the prior spin's outcome.
