If marbles are chosen, without replacement, from a bag of 10 blue and 5 red marbles, then the probability of getting a red marble followed by 2 blue marbles is

1. (A)\frac{5}{15} \times \frac{10}{14} \times \frac{9}{13}
2. (B)\frac{5}{15} + \frac{10}{14} + \frac{9}{13}
3. (C)\frac{5}{15} + 2\left(\frac{10}{15}\right)
4. (D)\frac{1}{5} \times \frac{2}{10}
