Question

q 18.) use the diagram to answer the question. how many possible outcomes are there for this experiment?

Explanation:

Step1: Analyze the tree - diagram

The diagram represents a two - step experiment (presumably coin - flips where H is heads and T is tails). The first branch has 2 options (H or T), and each of those branches has 2 further options.

Step2: Count terminal nodes

The terminal nodes of the tree - diagram represent the possible outcomes. Counting them, we have 4 terminal nodes: HH, HT, TH, TT.

Answer:

4
