Green Bridge Learning Resource Nchekwa Maka Possibility And Tree Diagrams

Gbogbo ọrọ náà

When events happen one after another, a tree diagram lays out every possible path and its probability. Multiplying along the branches and adding the relevant paths turns a tangled problem into clear, step-by-step arithmetic.

In this lesson you will use possibility (sample space) diagrams and tree diagrams, including successive selection with or without replacement.
