This Grade 4 hard worksheet challenges students with multi-step graph questions and prediction tasks. Multiple choice items ask about scaling small samples up to one hundred outcomes, totaling three-bar graphs, and simplifying probability fractions to lowest terms. Fill-in problems extend to larger tally counts and combined bar totals. Students reason carefully about likelihood and data, sharpening accuracy for tougher tests and assessments at school.

Part A: Multiple Choice
Circle the best answer for each question.
1. A spinner landed on red 8 of 20 spins. About how many reds in 100 spins?
A) 40
B) 30
C) 20
D) 60
2. A bar graph shows 7 dogs, 4 cats, and 9 birds. How many pets total?
A) 18
B) 20
C) 21
D) 19
3. If 3 of 12 marbles are green, what is the probability of green?
A) 1/2
B) 1/3
C) 1/4
D) 1/6
4. A tally chart shows 4 bundles and 2 extras. What is the count?
A) 20
B) 24
C) 26
D) 22
Part B: Fill in the Blank
Write the correct answer on each line.
1. If 6 of 30 spins land blue, predicting 100 spins gives about 20 blues.
2. A bag has 5 red and 5 yellow. Probability of red equals 5/10.
3. A bar graph shows 12 boys and 8 girls. The total students count is 20.
4. A tally chart of 7 bundles and 3 extras totals 38.
5. If 4 of 16 cards are stars, the probability of star simplifies to 1/4.
