just the nature of your answer should tell you that it's incorrect. you can't have a probability greater than 1. now the chart tells you the frequency of choosing the different combinations: 2 reds, 1 red 1 blue, or 2 blues. Note that all these frequencies add up to 12. now the chart says that the frequency of choosing 2 red marbles is 6. it means out of 12 trials, we would get 2 red marbles approximately 6 out of those 12 times we do the experiment. so now, what do you think the probability is?
