# Probability

Learn and practice finding event probabilities with interactive resources from GeoGebra.

## Middle School

GRADES 6-8

### Certain, Likely, Unlikely, Impossible Events

Indicate the probability of a chance event with or without models as certain, impossible, more likely, less likely, or neither likely nor unlikely using benchmark probabilities of 0, 1/2, and 1.

### Complement of an Event

Determine the complement of an event.

### Counting Strategies for Sample Spaces

Determine the sample space for an event using counting strategies (include tree diagrams, permutations, combinations, and the fundamental counting principle).

### Frequency Tables, Line Plots and Bar Graphs

Interpret probability models for data from simulations or for experimental data presented in tables and graphs (frequency tables, line plots, bar graphs).

### Probabilities in Geometry

Determine a simple probability using geometric figures.

### Probability of an Event as Fractions or Ratios

Describe the probability of a chance event using a fraction or ratio.

### Probability of Compound Events

Determine the probability of compound events (with and without replacement).

### Simulations to Estimate Probabilities of Compound Events

Determine a simulation, such as random numbers, spinners, and coin tosses, to model frequencies for compound events.

### Theoretical vs. Experimental Probability

Determine the probability from experimental results or compare theoretical probabilities and experimental results.

### Using Theoretical and Experimental Probability to Make Predictions

Make predictions based on theoretical probabilities or experimental results.
