Probability Calculator
Three modes for common probability problems: basic probability from outcomes, combined probability for two events (with AND/OR options), and complement probability. Useful for stats homework or just satisfying curiosity.
How to use
- For basic probability, enter how many favourable outcomes and how many total outcomes there are.
- For two events, switch to that tab and enter the probability of each event as a percentage.
- The complement tab finds P(A') - the probability that A does NOT happen.
