What is Probability?
In Mathematics, Probability theory is the study of chances. In real life, we predict chances depending on the situation. But Probability theory is bringing a mathematical foundation for the concept of Probability. For example, if a box contain 10 balls which include 7 black balls and 3 red balls and randomly chosen one ball. Then the Probability of getting red ball is 3/10 and Probability of getting black ball is 7/10. When coming to statistics, Probability is like the back bone of statistics. It has a wide application in decision making, data science, business trend studies, etc.
How to Calculate Probability of Event A or B Occurring?
Probability of Event A or B Occurring calculator uses Probability of Occurrence of Event A or Event B = Probability of Event A+Probability of Event B-Probability of Occurrence of Event A and Event B to calculate the Probability of Occurrence of Event A or Event B, The Probability of Event A or B Occurring formula is defined as the likelihood that event A or B occur where A and B are mutually inclusive events, i.e. the events can happen at the same time. Probability of Occurrence of Event A or Event B is denoted by P_{(A∪B)} symbol.
How to calculate Probability of Event A or B Occurring using this online calculator? To use this online calculator for Probability of Event A or B Occurring, enter Probability of Event A (P_{(A)}), Probability of Event B (P_{(B)}) & Probability of Occurrence of Event A and Event B (P_{(A∩B)}) and hit the calculate button. Here is how the Probability of Event A or B Occurring calculation can be explained with given input values -> 0.45 = 0.5+0.2-0.1.
