🎒 Part 1: Setting Up Your Experiment

1. Look at your grab bag. Count how many counters of each colour you have and record below:

Red counters: _______ Blue counters: _______ Green counters: _______ Yellow counters: _______

Total counters in bag: _______

2. Before you start drawing, predict which colour you think you will draw most often. Circle your prediction:

Red

Blue

Green

Yellow

3. Explain why you made this prediction:

📊 Part 2: Recording Your Results

4. Conduct 20 draws from your grab bag (remember to replace the counter each time!). Use tally marks to record your results:

Red: _________________________ Total: _____

Blue: _________________________ Total: _____

Green: _________________________ Total: _____

Yellow: _________________________ Total: _____

5. Convert your tally results into fractions. Remember: your fraction shows (number of times drawn) ÷ (total draws)

Red: _____ out of 20 = _____/20

Blue: _____ out of 20 = _____/20

Green: _____ out of 20 = _____/20

Yellow: _____ out of 20 = _____/20

🗣️ Part 3: Probability Language

6. Using the words certain, likely, unlikely, and impossible, describe each event:

Drawing a red counter is: ________________

Drawing a blue counter is: ________________

Drawing a green counter is: ________________

Drawing a yellow counter is: ________________

Drawing a purple counter is: ________________

Drawing any colour counter is: ________________

7. Order the colours from LEAST likely to MOST likely based on your experiment results:

1. _____________ (least likely)

2. _____________

3. _____________

4. _____________ (most likely)

🤔 Part 4: Thinking About Probability

8. Compare your prediction from Question 2 with your actual results. Were you correct?

Yes, my prediction was correct

No, my prediction was incorrect

9. Explain why your results turned out the way they did:

10. If you conducted this experiment 100 times instead of 20 times, what do you think would happen to your results?

🌍 Part 5: Real-Life Connections

11. Match each real-life situation with the correct probability term:

1. The sun will rise tomorrow

2. It will snow in Darwin in July

3. You will get heads when flipping a coin

4. You will roll a 6 on a dice

A. Unlikely

B. Certain

C. Equally likely

D. Impossible

12. Think of your own example for each probability term:

Certain: _________________________________________________

Likely: _________________________________________________

Unlikely: _________________________________________________

Impossible: _________________________________________________

13. Draw a picture showing your grab bag experiment:
