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.

WebDetermining the sample events’ probability that is occurring is honestly: sum the possibilities together. For instance, if one has a 20% possibility of obtaining $20 and a 35% possibility of winning $30, the overall probability of obtaining something will be 20% + 35% = 55%.
