📊 Part 1: Understanding Likelihood

1. Match each event to its likelihood by drawing a line:

Rolling a 7 on a standard die

The sun will rise tomorrow

Flipping heads on a fair coin

Drawing a red ball from a bag of only blue balls

Certain

Equally likely

Impossible

2. Which event is most likely to happen?

Rolling a number less than 7 on a standard die

Rolling exactly 6 on a standard die

Rolling a number greater than 6 on a standard die

Rolling an even number on a standard die

3. Circle all the events that are impossible:

Drawing a green marble from a bag containing only red and blue marbles

It will snow in Brisbane tomorrow in January

Rolling a 3 on a standard die

A month having 32 days

📏 Part 2: Number Line Placement

4. Look at the number line below. Place these events by writing the letter in the correct position:

A: Rolling an even number on a die (2, 4, or 6)

B: Drawing a red card from a deck of only black cards

C: The next baby born will be a boy or a girl

D: It will rain sometime this year in Queensland

Impossible ______|______|______|______|______ Certain

0 0.25 0.5 0.75 1

5. Order these events from least likely to most likely by numbering them 1-4:

____ Rolling a 6 on a standard die

____ Tomorrow will be a weekday

____ Picking a vowel from the letters A, E, I, O, U

____ A coin landing on tails

6. Explain why you placed "Rolling a 6 on a standard die" where you did in question 5:

🎯 Part 3: Real-World Probability

7. Mrs Chen's class has 12 boys and 8 girls. If she picks a student randomly to help, is it more likely to be a boy or a girl? Explain your reasoning:

8. Create your own probability scenario and explain where it would go on the number line:

My scenario: ________________________________________________

This would be positioned at approximately _______ on the number line because:

9. Extension Challenge: If you change the scenario in question 7 so there are equal numbers of boys and girls, how would this affect the likelihood? Explain:
