For each of the following, state whether the process described represents a discrete random variable, a continuous random variable, or not a random variable at all. Remember that the results of a process defining a random variable must be a numerical value of some kind (e.g. winnings at a casino, amount paid to insured customers, number of people in an area.) c) Draw one M &M from a bag. Observe whether it is blue, green, brown, orange, red, or yellow. d) Record the weight, in pounds, of every fish you catch during a day of fishing. e) Several major league baseball pitchers are asked to throw a ball as far as they can. The distance is recorded. f) You have a bag with 10 blue marbles, 10 green marbles, and 10 red marbles. Draw marbles one at a time from the bag. Keep going until you get a red marble. Stop and count the total number of marbles drawn before the red marble.
