Question

jude has a deck of playing cards. he is asked to remove one card at random, then a second card. what could jude do between the events to ensure they are dependent?
he could get a new, complete deck of playing cards.
he could return the first card back to the original deck.
he could put the first card he removed into his pocket.
he could choose to not remove the second card.

Explanation:

Dependent events mean the outcome of the first event affects the probability of the second. If the first card is kept (not returned), the deck size and card composition change for the second draw, making the events dependent. Returning the card or using a new deck keeps probabilities independent, and skipping the second card is not a valid two-event scenario.

Answer:

He could put the first card he removed into his pocket.
