Suppose that you have a deck of playing cards, and you draw one card after thorough shuffling. you only care about the value of the card, you put the card back after drawing, and you define the values for each card as follows: aces are 1, the numbered cards have the value corresponding to the number on the card, and face cards are all worth 10. (a) what is the expected value of this experiment? (b) what is the variance?
