Hello! I have no idea with how do I even approach this probability problem. Thank you in advance..!
![**Problem 5.** Let \( X \) be a continuous random variable with probability density
\[
f_X(x) =
\begin{cases}
1/6, & -2 \leq x \leq 0, \\
2/9, & 0 < x \leq 3, \\
0, & \text{otherwise}.
\end{cases}
\]
(a) Compute \( \mathbb{E}[X] \).
(b) Compute \( \text{Var}(X) \).
(c) Compute \( \mathbb{E}[(X - 1)^2] \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F25ecc335-25be-4ebd-8f8c-629ee64b2629%2Fdc0cd0fa-0bb9-43b3-87af-8f32147631b2%2F991c4y_processed.png&w=3840&q=75)
