What is probability? The probability of anything means the odds or chance of it taking place. The value of the probability varies between 0 to 1. If it is 1, this means the event will certainly occur while 0 means there is no chance of the event happening.
Probability calculator finds the possibility of an event occurring from a number of events. The tool uses the probability formula containing the number of outcomes and the times the event occurs.
The result includes the chance of an event taking place and of its not taking place. Values are represented in both decimals and percentages.
