To determine the probability of selecting marbles with a tree graph without replacement, you need to calculate the probability of each branch of the tree graph. For example, if the tree graph has three branches, you would calculate the probability of each branch by multiplying the probability of each event in the branch. For example, if the first branch has a probability of 0.2, 0.3, and 0.4, then the probability of that branch would be 0.2 x 0.3 x 0.4 = 0.024. You would then repeat this process for each branch of the tree graph and add the probabilities together to get the total probability of selecting marbles without replacement.
