Combinatorics & Probability; Quantitative Reasoning practice

Counting arrangements, selections, and chances — plus the binomial theorem. These questions punish the two classic mistakes: double-counting and forgetting whether order matters. NEAT-style questions stay accessible (no advanced distributions) but expect clean casework. If you can explain *why* a formula divides by k!, you're ready.
