Answer:
He could put the first card he removed into his pocket
Step-by-step explanation:
With regards to the above, he could put the first card he removed into his pocket so that the amount of card he has to draw the second time will be affected hence make it dependent.
Take for instance, there are 52 cards in total, if he picks the first card and did not replace it, then the probability of taking second card will be 50/51 since the total cards left in the deck is now 51.
Keeping the card out of the deck can be done to ensure that the events are dependent.
Probability is a measure of the likeliness of an event to occur and it is measured between 0 to 1 , where 0 represents unlikeliness of the event and 1 represents certainty.
It is given in the question that he would have to keep the first card out of the deck before removing the second card.
Two events are dependent if the probability of one event changes based on the result of the other.
To be clear, an action on its own (like drawing a card) is not an event. An event is a possible outcome (or set of outcomes) we could observe.
Since we assume all 52 cards have an equal chance of being drawn on the first pick (that being 152), the only way to change this probability for the second pick is to keep the first card out of the deck.
This reduces the size of the deck to 51, meaning each remaining card has a 51 chance of being picked—except for the card he drew first, which now has a 0% chance of being drawn again.
Therefore keeping the card out of the deck can be done to ensure that the events are dependent.
