The probability that a face card can be drawn from a standard deck of cards is 12/52 which can be simplified into 3/13.
The expected value is the product of the probability and the value.
Expected value = (3/13)($1) = $0.23
The difference between the amount spent and the expected value is equal to $0.27.
Rent for 6 hours = 21
rent for a hour = 21/6
= $3.5
