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