Probability and Predictions

What Are the Chances?

Probability measures how likely something is to happen, from 0 (impossible) to 1 (certain).

Calculating Probability

Probability = \( \frac{\text{Number of Favorable Outcomes}}{\text{Total Outcomes}} \)

Making Predictions

Knowing probabilities helps you predict outcomes, like the chance of rain or winning a game.

Real-Life Applications

Probability is used in games, weather forecasts, and making decisions.

Fun to Try

Flip a coin! Probability of heads: \( \frac{1}{2} \).

Examples

  • Rolling a die: probability of getting a 3 is \( \frac{1}{6} \).

  • Predicting the chance of rain based on weather data.

In a Nutshell

Probability is the math of chance and helps make predictions.
