In a bag there are 3 red and 2 blue balls. If one ball is drawn, what is the probability of red?

• A. 3/5
• B. 1/2
• C. 2/5
• D. 4/5

Answer: (A)

Probability is the number of favorable outcomes divided by the total number of equally likely outcomes. There are 5 balls in the bag, so 5 equally likely draws. Three of these are red, so the favorable outcomes are 3. Therefore the chance of drawing red is 3/5 (0.6). The option that shows 3/5 is the correct one. The other fractions would require different counts of red or total balls (e.g., 2/5 would mean only two red balls, 4/5 would mean four red balls).
