This worksheet provides targeted practice for Grade 7 students on calculating the probability of compound events, specifically mutually exclusive and overlapping events. Through two focused problems involving a spinner and a coin flip, students apply the addition rule for probability and express their answers as percentages, reinforcing this key concept from the statistics and probability domain.
At a Glance

- Standard:
CCSS.MATH.CONTENT.7.SP.C.8— Find probabilities of compound events using organized lists, tables, or simulation.- Skill Focus: Probability of mutually exclusive and overlapping events
- Format: 1 page · 2 problems · Answer key included · PDF
- Best For: Targeted skill practice, exit ticket, or homework.
- Time: 5–10 minutes
What's Inside
This single-page PDF worksheet provides the formula for mutually exclusive events, P(A or B) = P(A) + P(B). It features two problems using a spinner and a coin flip. A full answer key is included on a separate page for quick grading.
Skill Progression
The worksheet follows a simple progression.
- Guided Practice: A definition and formula are provided as a direct reference.
- Supported Practice: The first problem uses a spinner to introduce an overlapping event in a structured context.
- Independent Practice: The second problem uses a classic coin flip for a purely mutually exclusive event, allowing students to apply the formula independently.
Standards Alignment
This resource aligns with Common Core standard CCSS.MATH.CONTENT.7.SP.C.8, which covers finding probabilities of compound events. The worksheet targets this standard by having students calculate probabilities for "A or B" events, a key part of compound probability. The standard code can be copied into lesson plans or curriculum maps.
How to Use It
Use this worksheet as an exit ticket after a lesson on compound probability to check for understanding. The expected completion time is 5-10 minutes. As a formative check, observe if students correctly identify the total number of outcomes for each scenario before applying the addition rule.
Who It's For
Designed for 7th graders, this resource can also work for 8th-grade review or 6th-grade acceleration. For extra support, pair it with a probability vocabulary anchor chart. The minimal design is accessible for students who find cluttered worksheets distracting.
This Grade 7 math worksheet provides targeted practice on standard CCSS.MATH.CONTENT.7.SP.C.8, focusing on the probability of compound events. Students must calculate the likelihood of mutually exclusive and overlapping events, a critical skill for developing statistical literacy. Research from Fisher & Frey (2014) emphasizes the importance of moving from guided to independent practice, a structure this worksheet follows by providing an initial formula and then two problems for application. By grounding abstract probability concepts in concrete examples like spinners and coins, this resource helps students build a conceptual foundation. According to the NAEP, a significant number of students struggle with probability, making focused, standards-aligned practice essential for mastery. This worksheet offers a concise tool for teachers to provide that practice, check for understanding, and prepare students for more complex statistical analysis.
