M&M Probability Fractions

Colourful M&Ms scattered on a plate

🍬 Part 1: M&M Investigation Setup

1. Count your M&Ms and record the total number below:

Total M&Ms: _________ (Tapeke katoa)

2. Sort your M&Ms by colour and count each colour:
Red (Whero): _____
Blue (Kikorangi): _____
Green (Kākāriki): _____
Yellow (Kōwhai): _____
Brown (Parauri): _____
Orange (Karaka): _____
3. What is the theoretical probability of drawing a red M&M? Write as a fraction:

P(red) = Number of red M&Ms / Total M&Ms = _____ / _____ = _____

4. Which colour has the highest probability of being selected?

🎲 Part 2: Experimental Probability (Tūponotanga)

5. Conduct 12 trials. Without looking, randomly pick one M&M, record its colour, then put it back. Record your results:
Trial 1: _____ Trial 2: _____ Trial 3: _____ Trial 4: _____
Trial 5: _____ Trial 6: _____ Trial 7: _____ Trial 8: _____
Trial 9: _____ Trial 10: _____ Trial 11: _____ Trial 12: _____
6. Count how many times you drew each colour:
Red: _____ times Blue: _____ times Green: _____ times
Yellow: _____ times Brown: _____ times Orange: _____ times
7. Calculate the experimental probability of drawing red as a fraction:

Experimental P(red) = Times red was drawn / Total trials = _____ / 12 = _____

8. Compare your theoretical and experimental probabilities for red M&Ms:

They are exactly the same

They are close but slightly different

They are very different

💭 Part 3: Reflection and Analysis

9. Explain why your theoretical and experimental probabilities might be different:
10. If you removed 2 red M&Ms from your collection, how would this change the probability of drawing red? Explain your reasoning:
11. Write one sentence in English or te reo Māori describing what you learned about probability and fractions today:
