Let's play cards

You have a regular deck of 52 well-shuffled playing cards. The deck consists of 4 suits, and there are 13 cards in each suite: ranks 2 through 10, a jack, a queen, a king, and an ace. This means that in the whole deck of 52, there are four of each distinct rank: four aces, four kings, four tens, four fives, etc.

Since there are 52 distinct cards, the probability of drawing any one particular card is 1/52. Using the two rules of probability you've learned about in the last video, calculate the probabilities of drawing some specific combinations of cards, as described in the instructions.
