1. Circle the probability word that best describes each event:

a) Rolling an even number on a dice: Certain Likely Unlikely Impossible

b) Picking a green marble from a bag of only red marbles: Certain Likely Unlikely Impossible

🔬 Part 2: Predictions and Experiments

2. Make predictions using probability words:

a) If you flip a coin, what do you predict will happen? _______________

b) If you roll a dice, is it more likely to get a number less than 4 or greater than 4? _______________

c) If you pick a counter from a bag with 6 blue and 2 yellow counters, which colour are you more likely to pick? _______________

3. Mini-Experiment: Coin Flipping

Flip a coin 5 times and record your results:

Flip 1: _______ Flip 2: _______ Flip 3: _______ Flip 4: _______ Flip 5: _______

How many heads? _____ How many tails? _____

5. What does "equally likely" mean? Give an example:

6. Why might the results of a small experiment (like flipping a coin 5 times) be surprising?

7. If you rolled a dice 6 times, would you expect to get each number (1, 2, 3, 4, 5, 6) exactly once? Why or why not?
