About This Worksheet

This easy-level worksheet contains 12 problems designed for 7th Grade students practicing experimental probability. Easy worksheets use simpler numbers and straightforward problem types to build confidence and reinforce foundational skills.

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

  • Express probabilities as exact fractions, with assumptions about equally likely outcomes stated explicitly.
  • Check your result using the method in the example before moving to the next question.

How to Solve: Worked Example

Example Problem: A fair coin is tossed 40 times and lands heads 8 times. What is the experimental probability of heads?
Solution Steps:
  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
Tip: Check your result using the method in the example before moving to the next question.
