Understanding Probability Calculations

Basic Probability Concepts

Probability measures the likelihood of an event occurring, expressed as a number between 0 (impossible) and 1 (certain), or as a percentage between 0% and 100%.

Types of Probability

This calculator handles two main types of probability calculations:

1. Independent Events: Where the outcome of one event doesn't affect the other's probability.

2. Series Events: Calculating probabilities across multiple occurrences of the same event.
