Formula of probability
Did you know?
WebProbability of an Event E is represented by P (E). For example, probability of getting a head when a coin is tossed is equal to 1/2. Similarly, probability of getting a tail when a coin is tossed is also equal to 1/2. Hence, the total probability will be: P (E) = 1/2 + 1/2 = 1. Know more about probability by clicking here.

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.
WebThe weather forecast shows these possibilities: 85% chance of no rain, 10% chance of rain, 5% chance of rain with thunderstorms. There are three possibilities in this scenario, but they are not equally likely possibilities. To have the outcomes be equally likely, they each have to happen just as often as each other.
