Question Analysis
This question involves the basic application of probability in a simple object - selection context.
The main focus is on correctly identifying the number of favorable outcomes (selecting a white sock) and the total number of possible outcomes (total number of socks in the box) to apply the probability formula.

Key Concept Explanation
The probability of an event is determined by dividing the number of favorable outcomes for that event by the total number of possible outcomes.
In this case, it helps us figure out the likelihood of picking a white sock from the box.

Step - by - Step Solution
First, find the total number of socks in the box. Add the number of white and black socks: socks.
The number of favorable outcomes (picking a white sock) is 5.
Apply the probability formula:
