Conditional Probability Explained Step by Step

Understand this probability question step by step.

Introduction

“Let’s understand this probability question step by step.” “Don’t worry about formulas right now — we’ll first understand the idea.”

Understanding the Given Data

“We are given a bag that contains three red balls and two blue balls.” “So in total, there are five balls in the bag.” “This is our starting situation.”

Understanding the GIVEN condition

“Now the question says — the ball is not blue.” “This is very important.” “It means blue balls are no longer possible.” “So we remove all blue balls from our thinking.”

New Possible Choices (Filtered Thinking)

“After removing blue balls, only red balls remain.” “There are three red balls.” “So the number of balls that satisfy the condition ‘not blue’ is three.”

Forming the Probability (No hurry)

“Now we form probability carefully.” “Probability means: number of favourable outcomes divided by total outcomes.” “Here, favourable outcomes are red balls — three.” “Total balls in the original bag are still five.” “So the probability becomes three divided by five.”

Final Answer + Concept Check

“So the correct answer is three by five.” “Remember this idea clearly.” “When you see the words ‘given that’, the condition filters the choices…” “but the total number of balls remains the original one.”

“Condition tells you what to count, not where to count from.”
