... the total number of cubes, or one-half: 1 green and 2 green and red. What does this mean? It means the probability of choosing a green cube from the envelope is 1 out of 2. In our second example, we’re going to have 3 cubes: 2 of one color and 1 of the second color. So, we have 2 reds and 1 is green ...
