Question:
The probability distribution for the number of students being absent in a class on a Saturday is as follows:
\begin{array}{|c|c|c|c|c|}
\hline
\mathbf{X} & 0 & 2 & 4 & 5 \\
\hline
\mathbf{P(X)} & p & 2p & 3p & p \\
\hline
\end{array}
Where \(X\) is the number of students absent.
\begin{array}{l}
\text{(i) Calculate } p. \\
\text{(ii) Calculate the mean of the number of absent students on Saturday.}
\end{array}
