Test your probability skills across six different games! The player(s) with the highest score advance to a bonus round. Most points wins!
A candy is hidden under one of three shells. Pick a shell, then we reveal an empty shell. Should you stay or switch?
Tip: Switching gives you a 2/3 chance of winning!
Two random numbers (1-50) are face down. You flip one. Guess if the hidden number is higher or lower.
Strategy: If your card is above 25, guess lower. If below 25, guess higher for better than 50% odds!
Predict what poker hand you'll be dealt. Points vary by hand rarity:
Note: "None of these" (high card) is actually most common!
Solve a probability problem with four possible answers. Questions involve counting, permutations, combinations, and probability calculations based on your difficulty level.
Level 1: Basic counting and combinations
Level 2: Complex arrangements and selections
Level 3: Advanced probability calculations
Match four probability questions to their correct answers. You get 1 point for each correct match.
Tip: Work through the math for each question systematically!
Given a probability expression with combinations, permutations, or factorials, simplify it to a reduced fraction.
Tip: Cancel common factors before multiplying large numbers!
All players with the highest score advance to the bonus round. A bowl with 40-60 candies and 40-60 cockroaches is shown.
All players estimate a probability involving draws from the bowl (with or without replacement). The closest estimate wins 5 bonus points!
Important: No two players can submit the same estimate.
