Question Analysis
This question involves using a tree diagram to calculate the probability of a specific pet choice.
The main focus is on finding the correct path in the tree diagram and multiplying the probabilities along that path to obtain the probability of choosing an adult cat.

Key Concept Explanation
Tree diagrams help in visualizing and calculating the probabilities of compound events.
Each path from the start of the tree to an end - point represents a possible outcome, and the probability of that outcome is the product of the probabilities of the branches along that path.

Step - by - Step Solution
First, identify the probability of choosing a cat. The probability of choosing a cat is 1/2.
Then, given that a cat is chosen, identify the probability of choosing an adult cat. The probability of choo...
