Question Analysis
This question involves using a tree diagram to calculate the probability of a specific outcome within a multi - step selection process related to music playlists.
The main focus is on identifying the correct sequence of branches in the tree diagram and multiplying the corresponding probabilities to obtain the probability of choosing a playlist with new rock music.

Key Concept Explanation
In a tree diagram representing a series of choices, the probability of a particular combination of choices is determined by multiplying the probabilities along the branches that lead to that combination.
Each branch represents a possible choice at a given step, and the probabilities associated with the branches indicate the likelihood of making that choice.

Step - by - Step Solution
First, identify the probability of choosing rock music: The probability of choosing rock music is 3/7.
Then, given that rock music is chosen, identify the probability of choosing new rock music: Given rock music is chosen, the ...
