Example 3 A bag has 4 red balls and 2 yellow balls. (The balls are identical in all respects other than colour). A ball is drawn from the bag without looking into the bag. What is probability of getting a red ball? Is it more or less than getting a yellow ball? Total Balls = 6 Number of Red Balls = 4 Number of Yellow Balls = 2 Probability of getting a red ball = (π‘π‘’π‘šπ‘π‘’π‘Ÿ π‘œπ‘“ 𝑅𝑒𝑑 π΅π‘Žπ‘™π‘™π‘ )/(π‘‡π‘œπ‘‘π‘Žπ‘™ π΅π‘Žπ‘™π‘™π‘ ) = 4/6 = 2/3 Probability of getting a yellow ball = (π‘π‘’π‘šπ‘π‘’π‘Ÿ π‘œπ‘“ π‘Œπ‘’π‘™π‘™π‘œπ‘€ π΅π‘Žπ‘™π‘™π‘ )/(π‘‡π‘œπ‘‘π‘Žπ‘™ π΅π‘Žπ‘™π‘™π‘ ) = 2/6 = 1/3 Since 2/3>1/3 ∴ Probability of getting a red balls is more than getting a yellow ball.
