There are 3000 marbles in a machine - 1000 red, 1000 green, and 1000 blue. The machine churns out a random number of marbles into a bag (any number from 1 to 3000), without letting you see the inside, so you don't know how many of each colour, or in total, there are. What is the probability, without looking into the bag, that you will pick out a red marble?
