Explanation:
To determine whether Alex is more likely to take a '3' card from Rex or from Nina, we need to compare the probabilities of drawing a '3' card from each of them.
Rex has four cards numbered 1 to 4, but we don't know the specific arrangement of the cards. Therefore, the probability of drawing a '3' card from Rex depends on how the cards are distributed. If Rex has a '3' card among his four cards, the probability of drawing it would be 1/4.
Nina, on the other hand, has five cards numbered 1 to 5. Since there is a '3' card among Nina's cards, the probability of drawing a '3' card from her is 1/5.
Comparing the probabilities, we can see that the probability of drawing a '3' card from Rex is higher (1/4) compared to drawing it from Nina (1/5). Therefore, Alex is more likely to take a '3' card from Rex
