(i) To find \(P(X = 3)\), we need the probability of drawing two red discs followed by a blue disc, i.e., \(P(RRB)\).

The probability of drawing the first red disc is \(\frac{2}{6}\), the second red disc is \(\frac{1}{5}\), and the first blue disc is \(\frac{4}{4}\).

Thus, \(P(X = 3) = \frac{2}{6} \times \frac{1}{5} \times \frac{4}{4} = \frac{1}{15}\).

(ii) The probability distribution table for \(X\) is as follows:

\(P(X = 1)\) is the probability of drawing a blue disc first, which is \(\frac{4}{6} = \frac{2}{3}\).

\(P(X = 2)\) is the probability of drawing one red disc followed by a blue disc, i.e., \(P(RB) = \frac{2}{6} \times \frac{4}{5} = \frac{4}{15}\).

\(P(X = 3)\) is already calculated as \(\frac{1}{15}\).
