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?

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
