Sample Spaces: Lists, Tables & Tree Diagrams — Easy Worksheet 1
Grade 7 · MathSheets Name: ____________________ Date: __________
Find the sample space (all the possible outcomes), then answer the question. Write probabilities as fractions in simplest form.
How to solve
The sample space is the list of every possible outcome. When one step has 2 outcomes and the next has 6, there are 2 × 6 = 12 outcomes in all — a tree diagram shows each branch. If all outcomes are equally likely, probability = (number of outcomes in the event) ÷ (number of outcomes in the sample space).
Example
You spin a spinner with 5 equal sections and then pick a card from 4 cards numbered 1 to 4. How many outcomes are in the sample space?
Answer: 20
Not quite. The answer is
💡 The spinner has 5 outcomes and the coin has 2. Each spinner result can go with each of the 2, so multiply: 5 × 2 = 10. There are 10 outcomes.
✓ Correct!

Not quite. The answer is
💡 The coin has 2 outcomes and the cube has 6, so there are 2 × 6 = 12 equally likely outcomes (H1, H2, …, T6). The outcomes with heads and an odd number are H1, H3, H5: 3 of them. P = 312. Simplify: divide the top and the bottom by 3: 312 = 14. The probability is 14.
