(07.02 LC) The number of marbles of different colors stored in a hat is listed below: 4 red marbles 10 green marbles 7 blue marbles Without looking in the hat, Dan takes out a marble at random. He replaces the marble and then takes out another marble from the hat. What is the probability that Dan takes out a blue marble in both draws? fraction 2 over 21 fraction 1 over 9 fraction 1 over 2 fraction 2 over 3

Step-by-step explanation:2 over 21

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
