Grade 4 students explore compound events with two-coin flips, four-equal-sector spinner outcomes, and predictions based on collected data. Each fill-in item asks Grade 4 learners to list sample spaces, count favorable outcomes, or multiply trials by probability. The matching section pairs probability vocabulary with key ideas, including theoretical and experimental probability. Items reinforce that equal sectors yield equal chances and that predictions multiply trials by probability fractions for compound events.

Probability and Data
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Flipping two fair coins, the chance of getting two heads is 1 in 4.
2. A spinner has 4 equal sectors. The chance of landing on red is 1 out of 4.
3. Out of 20 spins, red came up 5 times. The experimental probability is 5 out of 20.
4. If the chance of rain is 1 in 5, then in 25 days you expect rain on about 5 days.
5. Flipping two coins, the chance of getting one head and one tail is 2 out of 4.
6. A spinner with sectors red, blue, green, yellow lands on green with chance 1 out of 4.
7. If a die shows 4 in 6 of 30 rolls, the experimental probability is 6 out of 30.
8. Two coins flipped 40 times, expect about 10 flips of two heads.
9. A 4-sector spinner spun 16 times should land on blue about 4 times.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Two-coin flip outcomes
→ HH, HT, TH, TT total four
HH, HT, TH, TT total four
Four-sector spinner
→ Each color has 1 in 4 chance
Each color has 1 in 4 chance
Experimental probability
→ Based on observed data counts
Based on observed data counts
Predicted outcomes
→ Multiply chance by total trials
