Drills

Constructing sample space grids and counting probabilities from them.

Author note — to cover

Fluency — listing or gridding every outcome of two spinners or two dice, and counting how many there are (4 questions).
Events from the grid — probabilities of totals, doubles and differences counted as cells over the whole grid (4 questions).
Unequal totals — comparing events such as a total of 7 against a total of 12, catching the assumption that every total is equally likely (4 questions).
