Question

Suppose we define a random variable for a deck of 52 cards such that every card is assigned a number equal to the number on the card. For aces, the cards are assigned a value of 1. For Kings, Queens, and Jacks, the cards are assigned a value of 10. What is the expectation of drawing a card? 6.33 7.125 8 7.82 None of the above are correct

Step 1

- The probability of drawing an Ace = 4/52 = 1/13 - The probability of drawing a King, Queen, or Jack = 12/52 = 3/13 - The probability of drawing any other numbered card = 36/52 = 9/13 Show more…
