Question Analysis
This question involves interpreting a two-stage probability scenario using a tree diagram structure.
The main focus is calculating the joint probability of two sequential events: book type selection followed by format choice.

Key Concept Explanation
Tree diagrams break down complex probability scenarios into sequential decisions
Joint probability requires multiplying probabilities along a specific path
Conditional probability reflects how choices at one stage affect subsequent probabilities

Step-by-Step Solution
Identify the correct path:
First: Customer chooses Non-Fiction (P(NF) = 45%)
Then: Chooses Paperback given Non-Ficti...
