Egg roulette: Part 2

In Part 1, students were introduced to probability without replacement, by exploring the game of egg roulette – 12 eggs, 3 raw and 9 cooked. Contestants take it in turns to choose an egg and smash it on their head hoping to avoid the 3 raw eggs! In this lesson, students consolidate and make deeper connections using simulation to address misconceptions on this abstract concept.
