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 Atleast One Event Occurring?
Probability of Atleast One Event Occurring calculator uses Probability of Occurrence of Atleast One Event = Probability of Event A+Probability of Event B+Probability of Event C-Probability of Occurrence of Event A and Event B-Probability of Occurrence of Event B and Event C-Probability of Occurrence of Event A and Event C+Probability of Occurrence of All Three Events to calculate the Probability of Occurrence of Atleast One Event, The Probability of Atleast One Event Occurring formula is defined as the likelihood that at least one of the events A, B, or C occurs which means any one or more of these events will happen, considering that they are mutually inclusive events, i.e. the events can happen at the same time. Probability of Occurrence of Atleast One Event is denoted by P_{(A∪B∪C)} symbol.
How to calculate Probability of Atleast One Event Occurring using this online calculator? To use this online calculator for Probability of Atleast One Event Occurring, enter Probability of Event A (P_{(A)}), Probability of Event B (P_{(B)}), Probability of Event C (P_{(C)}), Probability of Occurrence of Event A and Event B (P_{(A∩B)}), Probability of Occurrence of Event B and Event C (P_{(B∩C)}), Probability of Occurrence of Event A and Event C (P_{(A∩C)}) & Probability of Occurrence of All Three Events (P_{(A∩B∩C)}) and hit the calculate button. Here is how the Probability of Atleast One Event Occurring calculation can be explained with given input values -> 1.185 = 0.5+0.2+0.8-0.1-0.16-0.4+0.08.
