From the $13$ 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).

   Step 1(a):

   Find the probability of selecting a face card.

   Step 2(a):

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

   Step 3(a):

   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, $2$, $3$, $4$ and J, Q, K, A as consecutive sequences).

   Step 1(b):

   Use the factorial function to find all possible $4$-card permutations. Since we are talking about consecutive sequences, order does matter.

   Step 2(b):

   Write a list of all possible $4$-card consecutive sequences.

   Hint:

   $P\ = \frac{\text{number of consecutive sequences}}{\text{number of all possible sequences}}$
