There is a bag with 600 cubes in it. Some of the cubes are red and some are black. You reach into the bag 30 times, each time picking a random cube, recording its color, and putting the cube back in the bag. You picked 17 black cubes and 13 red cubes. With this information what is the best estimate you can make for how many red cubes and how many black cubesare in the bag? Describe how to calculate this best estimate and explain why your method of calculation makes sense.
