This Grade 4 easy worksheet introduces probability vocabulary and basic data reading. Students decide whether events are certain, likely, unlikely, or impossible using coins, marble draws, and dice. Short fill-in questions cover tally bundles and bar graph values, while spot-the-mistake items correct common reasoning errors. Two short answers ask learners to explain probability and tally charts in their own words clearly.

Probability and Data
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Flipping a coin and getting heads is impossible.
Rewrite: Flipping a coin and getting heads is likely.
2. Fix the sentence:
Pulling a red marble from a bag of only blue marbles is certain.
Rewrite: Pulling a red marble from a bag of only blue marbles is impossible.
3. Fix the sentence:
Rolling a number less than 7 on a standard die is unlikely.
Rewrite: Rolling a number less than 7 on a standard die 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. An event that cannot ever happen is called impossible.
3. On a tally chart, four straight marks plus one slash equals 5.
4. If a bar reaches the number 8 on a bar graph, the count is 8.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Why is rolling a 3 on a six-sided die unlikely but not impossible?
Only one face shows 3 out of six faces, so it can happen but probably will not on any single roll.
2. How does a tally chart help you read data quickly?
Tally marks group counts in fives, so you can skip-count by fives and add the leftover marks to find totals.
