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. WebJan 2, 2024 · Simplified, the probability is . 3 Determine the probability of the second event happening, given that the first event already happened. [9] To do this, you will need to examine how the first event happening will affect the number of favorable and possible outcomes of the second event.
