Question Analysis
This question involves using a tree diagram that represents real - world choices and their associated probabilities to calculate the probability of a specific combination of choices.
The main focus is on understanding conditional probabilities within the tree diagram and multiplying the correct probabilities to find the desired outcome.

Key Concept Explanation
The tree diagram shows the probabilities of different lunch and drink choices.
To find the probability of a particular combination (in this case, pizza and water), we multiply the probability of choosing pizza by the probability of choosing water given that pizza was chosen.
This is based on the multiplication rule for dependent probabilities in a tree - diagram context.

Step - by - Step Solution
The probability of choosing pizza is 3/5.
Given that pizza...
