Common Mistakes to Watch For

• Mixing up unlikely and impossible: unlikely events still happen sometimes, but impossible events never happen because zero outcomes match the event being asked about.
• Forgetting that each tally bundle equals five, not four, so students miscount totals when bundles include the diagonal slash mark across them.
• Using the matching outcomes count as the denominator in a probability fraction instead of the total outcomes, which flips the fraction upside down.
