Tap cells of the two-device outcome grid to shade a compound event — AND, OR, NOT — and read its probability as shaded over total, then predict how many of N trials will hit and watch the simulation land.
Two random devices — coin, die or spinner — decide every café order, and the player shades the favourable cells of the outcome grid by hand, reading P(event) as shaded cells over all cells. OR and NOT events on the same grid expose the double-counting misconception (a cell can only be shaded once), and a predict mode dials the expected hits in N trials before a live simulation lands beside the prediction. Best for Grades 7–8.
