You use some combinations so often … WebProbability is: (Number of ways it can happen) / (Total number of outcomes) Dependent Events (such as removing marbles from a bag) are affected by previous events. Independent events (such as a coin toss) are not affected by previous events. We can calculate the probability of two or more Independent events by multiplying.
