**Question:** Suppose that the p.d.f. of a random variable \( X \) is as follows:

\[
f(x) = 
\begin{cases} 
\frac{1}{8} x & \text{for } 0 \leq x \leq 4 \\
0 & \text{otherwise.}
\end{cases}
\]

a. Find the value of \( t \) such that \( P(X \leq t) = 1/4 \).

b. Find the value of \( t \) such that \( P(X \geq t) = 1/2 \).
