A dependent event occurs when the outcome of one event affects the outcome of another event.
Among the options provided, the correct representation of 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 available options for the second snack, making the events dependent on each other.
The other options describe scenarios that do not reflect dependency between events.
