Use the information to answer the questions below.
There are four pieces of bubble gum left in a quarter machine. Two are red and two are yellow. Chandra puts two
quarters in the machine. One piece is for her and one is for her friend, Kay. If the two pieces are the same color, she is
happy because they will not have to decide who gets what color. Chandra claims that they are equally likely to get the
same color because the colors are either the same or they are different. Check her claim by doing a simulation.
