Classical probability: sample space and events

MathematicsProbabilityAges 15–16

List out the entire sample space Ω when tossing 2–3 coins or rolling 1–2 dice (shown as a 6 × 6 grid with dice faces drawn as pips). Students pick a ready-made event or click individual outcomes to build a custom event A, seeing n(A), n(Ω), and P(A) = n(A)/n(Ω); click 'Run N trials' to watch the experimental frequency settle toward the theoretical probability.
