Complementary Events & Probability Range

Master probability fundamentals through immersive visual storytelling

Welcome to the fascinating world of probability! Discover complementary events and probability ranges through engaging animations.
🔄 Complementary Events

When an event E occurs, its complement Ē represents all outcomes where E doesn't occur. Together, they cover all possible outcomes in the sample space.

P(E) + P(Ē) = 1
📏 Probability Range

All probabilities must fall between 0 and 1, inclusive. This fundamental constraint ensures mathematical consistency in probability theory.

0 ≤ P(E) ≤ 1
🎯 Impossible Events

Events that can never happen have a probability of 0. These represent empty sets in the sample space with no possible outcomes.

P(Impossible) = 0
✅ Certain Events

Events that must always happen have a probability of 1. These represent the entire sample space where all outcomes satisfy the event condition.

P(Certain) = 1
