In a sample space of nine equally likely outcomes, let event A contain 5 elements and event B contain 6 elements, with their intersection containing 2 elements. The conditional probability is calculated directly as the size of the intersection divided by the size of B: .
Conditions: The sample space has nine equally likely outcomes.; Event A has 5 elements, Event B has 6 elements, and has 2 elements.
