Question Analysis
This question involves calculating the probability of non - mutually exclusive events within the context of smartphone features in a tech store.
The main focus is on determining the individual probabilities of each feature and the probability of their intersection, then applying the formula for non - mutually exclusive events.

Key Concept Explanation
For non - mutually exclusive events A (smartphone has a high - resolution camera) and B (smartphone has a large battery capacity), the formula is used.
This formula ensures that smartphones with both features are not double - counted when calculating the probability of having either feature.

Step-by-Step Solution
The probability that a smartphone has a high - resolution camera, .
The probability that a smartphone has a large battery capacity, .
The probability that a smartphone has both features,
