1. Let \( X \) be a continuous random variable with cumulative distribution function (cdf)

\[
F(x) = 
\begin{cases} 
0, & x \leq 0 \\
\frac{x^2}{4}, & 0 \leq x < 2 \\
1, & 2 \leq x
\end{cases}
\]

a. Find \( P(X \leq 1) \), \( P(1 \leq X \leq 1.5) \), and \( P(X > 1.5) \).

b. Derive the probability density function (pdf) of \( X \).

c. Find the median and 75th percentile of the random variable.
