Question Analysis
This question involves using a tree diagram to calculate the probability of a specific combination of events in the context of sandwich selection.
The main focus is on identifying the correct sequence of branches in the tree diagram and multiplying the corresponding probabilities to find the probability of the desired outcome.

Key Concept Explanation
In a tree diagram representing a series of choices or events, the probability of a particular combination is found by multiplying the probabilities along the branches that lead to that combination.
Each branch represents a possible choice, and the probabilities on the branches indicate the likelihood of that choice being made.

Step - by - Step Solution
First, identify the probability of choosing white bread: The probability of choosing white bread is 1/3.
Then, given that white bread is chosen, identify...
