7.SP.C.8 Tutor Intake -- Compound Events: Sample Spaces and Simulation

This short check helps your tutor see where to start. Work on your own,
without a calculator. If you're unsure, give your best try — the goal is
to find what to work on together, not to grade you.

Procedures

A tree diagram for flipping a coin 3 times has 2 branches at the
first level, 4 nodes after the second level, and 8 endpoints
(leaves) after the third level. How many total outcomes are in
the sample space?

14 — the sum of branches, nodes, and endpoints at every level

2 — the number of branches at just the first level

4 — the number of nodes after the second level

8 — the number of complete paths from root to leaf (the number of endpoints)
