In probability, a dependent event is an event where the outcome or occurrence of one event affects the outcome or occurrence of another event.
Among the options provided, the scenario that represents a dependent event is:
picking 2 snacks from the pantry without looking and keeping the first one before selecting the second one.
In this case, the selection of the first snack affects the choices available for the second snack, making it dependent. The other options either involve replacement or have no influence on the subsequent event.
