Question Analysis
This question involves using a tree diagram to find the fraction of a specific type of outcome within all possible outcomes.
The main focus is on identifying the relevant path in the tree diagram that represents an outdoor activity other than hiking and calculating its probability as a fraction of the total possible activities.

Key Concept Explanation
To find the fraction of a particular outcome in a tree - diagram - based scenario, we calculate the probability of that outcome by multiplying the probabilities along the relevant branches.
Then, we can express this probability as a fraction of the total (since the sum of probabilities of all possible outcomes is 1).

Step - by - Step Solution
Calculate the probability of choosing an outdoor activity and then biking (an outdoor activity other than hiking).
The probability of choosing a...
