In a bag containing 10 balls, there are 6 red balls and 4 blue balls. If 3 balls are drawn at random without replacement, what is the probability that exactly 2 of the drawn balls are red?
Use the formula for probability:
$$P(X) =\frac{n(X)}{n(S)}$$
where:
- $n(X)$ is the number of favorable outcomes.
- $n(S)$ is the total number of outcomes.
