Module 3 Pre-Assessment

Test your baseline knowledge of probability concepts

5 questions • Not graded • Helps measure your learning progress

Instructions

This pre-assessment helps you see what you already know about probability before starting the module. Don't worry if you don't know the answers—that's perfectly normal! This is just your starting point.

Answer all 5 multiple-choice questions
This is not graded and won't affect your progress
At the end of Module 3, you'll take the same assessment again to see your improvement

What This Score Means

This is your baseline score—it shows what you knew before learning the material. Don't worry if your score is low! That's completely normal and expected.

After completing Module 3, you'll retake this same assessment. The difference between your pre-assessment and post-assessment scores will show how much you've learned!
