📌 The number of favorable outcomes (2 red and 2 blue) is:

📌 \binom{7}{2} \times \binom{9}{2} = \left(\frac{7 \times 6}{2 \times 1}\right) \times \left(\frac{9 \times 8}{2 \times 1}\right) = 21 \times 36 = 756

📌 Therefore, the probability is:

📌 \frac{756}{1820} = \frac{189}{455}

📌 So, the probability of drawing exactly two red marbles is $\boxed{\dfrac{189}{455}}$

📌 Question: If I roll a fair six-sided die four times, what is the probability that I roll the number 4 exactly twice?

📌 Solution: This is a binomial probability problem with $ n = 4 $ trials (rolls), success probability $ p = \frac{1}{6} $ (rolling a 4), and we want exactly $ k = 2 $ successes.

📌 The binomial probability formula is:
