There is a bag with 200 snap cubes in it. Some of the snap cubes are red and some are black. You reach into the bag 50 times, each time pulling out a snap cube, recording its color, and putting the snap cube back in the bag. You picked 12 black snap cubes and 38 red snap cubes. With this information, what is the best estimate you can make for how many red snap cubes and how many black snap cubes are in the bag? Explain why you expect your answer to give a good estimate for the number of red snap cubes and the number of black snap cubes in the bag.
Suppose you have a penny, a nickel, a dime, and a quarter in a bag. You shake the bag and dump out the coins. What is the probability that exactly 2 coins will land heads up and 2 coins will land heads down? Is the probability 50% or not? Solve this problem by drawing a tree diagram that shows all the possible outcomes when you dump the coins out.
