A bag contains 4 red and 6 black balls. Two balls are drawn in succession without replacement. The probability that the first is red and the second is black is |
$\frac{2}{5}$ $\frac{2}{3}$ $\frac{4}{15}$ $\frac{6}{25}$ |
$\frac{4}{15}$ |
The correct answer is Option (3) → $\frac{4}{15}$ ** Total balls = 4 red + 6 black = 10 Probability(first red) = $\frac{4}{10}$ After drawing one red, remaining balls = 9 (3 red + 6 black) Probability(second black) = $\frac{6}{9}$ Required probability = $\frac{4}{10} \times \frac{6}{9} = \frac{24}{90} = \frac{4}{15}$ Final Answer: $\frac{4}{15}$ |
