This Grade 5 starter sheet introduces probability vocabulary using everyday tools like coins, dice, and marble bags. Students sort events as certain, likely, unlikely, or impossible while writing simple fractions like 1/2 and 1/6 carefully. Short-answer prompts ask learners to explain when an event must always happen, building strong intuition before formal probability work and fraction notation begins in middle school.

Probability and Statistics
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The probability of flipping heads on a fair coin is 1/3.
Rewrite: The probability of flipping heads on a fair coin is 1/2.
2. Fix the sentence:
Rolling a 7 on a standard six-sided die is likely.
Rewrite: Rolling a 7 on a standard six-sided die is impossible.
3. Fix the sentence:
If a bag has only red marbles, drawing red is unlikely.
Rewrite: If a bag has only red marbles, drawing red is certain.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. An event that will definitely happen is called certain.
2. The probability of flipping tails on a fair coin is 1/2.
3. Rolling a 4 on a standard six-sided die has probability 1/6.
4. An event that cannot happen is called impossible.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Describe the chance of pulling a blue marble from a bag with 1 blue and 9 red marbles.
The chance is unlikely because only 1 out of 10 marbles is blue, giving probability 1/10.
2. Explain why rolling a number less than 7 on a standard die is certain.
Every face on a die shows 1, 2, 3, 4, 5, or 6, and all are less than 7, so the event always happens.
