There are a total of 3 groups Julio could be assigned to in the first session. For each group, there is a 1/3 chance that he will be assigned to that group.
In the second session, he must be assigned to the same group he was assigned to in the first session. So the probability of that happening is 1/3.
Therefore, the overall probability is 1/3 * 1/3 = 1/9.
This can also be expressed as 1/3 + 1/3 + 1/3 = 1/3.
So the probability that Julio will be assigned to the same color for both sessions is 1/3.
Julio is attending a summer camp. It has two sessions, and participants are divided into three groups: Red, Yellow, and Green. Participants will be randomly assigned to each color in each session. What is the probability that Julio will be assigned the same color for both sessions?(1 point)
