Probability: The First 100 Digits of Pi

Build number sense while finding the probability of randomly selecting each digit in the first 100 digits of pi in this engaging math worksheet! Pi is the ratio of the circumference of any circle to the diameter of that circle, and it is also an irrational number. In this probability and pi-centric worksheet, students will first determine the frequency of each digit in the first 100 digits of pi using a frequency table. Then learners will find the probability of randomly selecting each digit—and express each as a fraction, decimal, and percent—before answering questions about the probabilities they find.

Ideal for seventh- and eighth-grade students, this worksheet is a fun and inviting way to explore pi while practicing sorting data and finding probabilities. To learn more about this famous irrational number, check out the What Is Pi? handout!
