Sample Spaces: Lists, Tables & Tree Diagrams — Mixed
Every first-stage branch splits into all the second-stage outcomes. Count the ends.
ExampleYou spin or throw a coin (heads or tails) and then a spinner (four equal sections).
The tree diagram below has the first stage drawn. Complete it, list the whole sample space, and find P(T, 4).
The first stage has 2 branches and each splits into 4, so the sample space has 2 × 4 = 8 outcomes: H, 1 · H, 2 · H, 3 · H, 4 · T, 1 · T, 2 · T, 3 · T, 4 Each is equally likely, so P(T, 4) = 18. A tree makes the multiplication visible — every branch of stage one carries a full copy of stage two.
1.You spin or throw a coin (heads or tails) and then a die (six faces).
The tree diagram below has the first stage drawn. Complete it, list the whole sample space, and find P(T, 3).
2.You use a spinner (three equal colors) and a spinner (three equal colors). Write an organized list of every outcome. How do you know you have not missed one?
3.You use a spinner (three equal colors) and a spinner (three equal colors).
Fill in the table so every cell holds one outcome. How many outcomes are there, and why does the table have that many cells?
