Grade 5 students continue practicing probability words while working with spinners, coins, and small marble groups in this gentle review sheet. They simplify fractions like 2/8 to 1/4 and decide whether outcomes are likely or unlikely. The sheet reinforces probability vocabulary alongside fraction sense, preparing students well for the harder mean and median problems coming up in the medium worksheets later this unit.

Probability and Statistics
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
On a spinner with 4 equal red sections, landing on red is unlikely.
Rewrite: On a spinner with 4 equal red sections, landing on red is certain.
2. Fix the sentence:
The probability of rolling an even number on a six-sided die is 1/6.
Rewrite: The probability of rolling an even number on a six-sided die is 1/2.
3. Fix the sentence:
Pulling a green marble from a bag of 5 red marbles is likely.
Rewrite: Pulling a green marble from a bag of 5 red marbles is impossible.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. On a spinner with 4 equal sections (1 blue, 3 yellow), P(yellow) = 3/4.
2. Rolling an odd number (1, 3, or 5) on a standard die has probability 1/2.
3. If 2 of 8 marbles are green, the probability of green is 1/4.
4. An event that probably will not happen is called unlikely.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. A bag has 3 red and 7 blue marbles. Is drawing red likely or unlikely? Give the probability.
Drawing red is unlikely because only 3 of 10 marbles are red, so the probability is 3/10.
2. Why is the probability of flipping heads or tails on a fair coin certain?
Every flip lands on either heads or tails, so the event always happens and the probability is 1.
