Question

Rihanna rolls a 4 sided fair die, then she selects at random, without replacement, as many cards from the deck as the number shown on the die. What is the probability that she gets at least one Queen? (In your solution, define the corresponding events and write down the given probabilities in terms of them. You do not need to simply your final answer.)

Recall: There are 52 cards in a deck, 4 different suits (Clubs, Spades, etc.) and 13 different denominations (Ace, Two, ..., King). Hint: Let Ni be the event that the number shown on the die is i, for i = 1, · · · , 4. Let Q be the event that she gets at least one Queen
