A bag contains 3 red and 2 blue balls. Two balls are drawn at random without replacement. The probability that both are red is:
A. 9/25
B. 3/10
C. 3/5
D. 1/2
Answer: Option B
Solution (By JKSSB Mock Tests)
P(both red) = (3/5) × (2/4) = 6/20 = 3/10. Without replacement, the probability changes after the first draw, requiring multiplication of conditional probabilities.
