Introduction
While throwing a dice, if an event is defined as a number less than four. Then an event occurs if outcome is a number less than four.
Pre-Requisites:
Idea about probability, sample space and event.
Real Life Question:
What are the chances that a number less than 4 appears on the top while throwing a dice?
