Experimental and Theoretical Probability Worksheets

Before you begin

Read tables and graphs, count outcomes, and calculate with fractions.

Worked example

A fair coin is tossed 40 times and lands heads 8 times. What is the experimental probability of heads?

1. Use the observed head count divided by the total number of trials.
2. The theoretical probability is 1/2, but the experimental fraction may differ.

Answer: 1/5
