In Summary
Probability is a measure of how likely an event is to occur. In the context of marbles, probability can be used to determine the likelihood of certain outcomes when drawing marbles from a bag.
Probability can be a useful tool for analyzing situations involving marbles or other random processes. By calculating the probabilities of different outcomes, you can make predictions and decisions based on the likelihood of certain events occurring.
