Description
Compute P(n, r) = n!/(n − r)! for ordered arrangement problems — racing podiums, locker combinations, seating orders.
Standards: CCSS HSS-CP.B.9 (use permutations and combinations to compute probabilities), HSS-MD.B.7 (analyze decisions with probability).
Each problem matches an answer in the design grid above. As students color in their answers, a symmetrical pattern appears. If the pattern looks right, the work is right — easy for students to catch mistakes and easy for you to spot-check at a glance.
Works for classwork, homework, extra practice, extra credit, or sub plans. The PDF includes the worksheet and answer key. Download the preview to see exactly what you'll receive.
