A bag contain 8 blue and 12 green balls. Two balls are drawn in succession without replacement. The probability that first is blue and second is green is
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → $\frac{24}{95}$ **
Total balls = $8 + 12 = 20$
Probability(first blue) = $\frac{8}{20}$
After one blue is removed, remaining: 7 blue, 12 green → total 19
Probability(second green) = $\frac{12}{19}$
Required probability = $\frac{8}{20}\times\frac{12}{19}=\frac{96}{380}=\frac{24}{95}$
