Question: Find the probability of getting 4 aces when 5 cards are drawn from an ordinary deck of cards. Which of the followings is the correct answer? (i) or (ii)?

(i) ((4C4)(48))/(52C5)

(ii) ((5P4)(48))/(52P5)

According to my textbook, (i) is the correct answer. Why? Why the order of selection is not important? Thank you.
