How likely something is to happen. Many events can't be predicted with total certainty. The best we can say is how likely they are to happen, using the idea of probability. When a coin is tossed, there are two possible outcomes: Also: When a single die is thrown, there are six possible outcomes: 1, 2, 3, 4, 5, 6.

Probability is all about how likely is an event to happen. For a random experiment with sample space S, the probability of happening of an event A is calculated by the probability formula n(A)/n(S).

From probability range to conditional probability, Bayes’ formula to independent events, our arsenal of formulas equips you with the tools to tackle any probability puzzle with confidence and precision.

We can use the formula to find the chances of an event happening. The formula of the probability of an event is: Or, Where, Note: Here, the favourable outcome means the outcome of interest. Sometimes, students get confused about the word “favourable outcome” with “desirable outcome”.

5 days ago · Here’s the thing: how you calculate the probability of two events happening depends on the relationship between the two events. There are three different ways events can be connected: Independent Events. Two events are independent if the outcome of one doesn’t affect the outcome of the other.
