What is Probability?

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

How Are Probabilities Calculated?

Different types of probability calculations: 1. Simple Probability = Favorable Outcomes ÷ Total Possible Outcomes 2. Compound Probability (Independent) = P(A) × P(B) 3. Complement Probability = 1 - P(A)

Common Applications

Statistics

Analyzing data and making predictions

Games

Calculating odds in games of chance

Risk Analysis

Evaluating business and project risks

Science

Predicting experimental outcomes

Tips for Probability Calculations

  • Always express probabilities as decimals between 0 and 1
  • For independent events, multiply individual probabilities
  • Use complement probability for "not happening" scenarios
  • Consider whether events are dependent or independent
