From the spades in a deck of cards, four are selected. Find the probability that: 

  1. Exactly one card is a “face” card (Jack, Queen, or King).

    Find the probability of selecting a face card.

    Find the probability of selecting a non-face card. Remember that the total number of cards has changed.

    Repeat step 2 twice more. Multiply all four probabilities together. Remember, the order the cards are drawn in does not matter.

  2. The cards form a consecutive sequence (count both A, , , and J, Q, K, A as consecutive sequences).

    Use the factorial function to find all possible -card permutations. Since we are talking about consecutive sequences, order does matter.

    Write a list of all possible -card consecutive sequences.
