![**Problem 4**
The probability density function (pdf) of \( X \) is given by:
\[
f(x) = \frac{4}{243}(27 - x^3) \quad \text{for } 0 < x < 3, \text{ and } 0 \text{ otherwise}.
\]
**Tasks:**
a) Calculate \( P(1 < X < 2) \).
b) Determine \( E(X) \), the expected value of \( X \).
c) Find the third moment of \( X \).
d) Compute \( E[X(2X^2 - 3) + 10] \).
In this problem, you will explore the properties of the given pdf over a specified range and compute various statistical measures by integration.](https://content.bartleby.com/qna-images/question/12050043-4d02-4d31-b9b4-7dfbc30a9c5d/8b2bad60-2d42-47fd-847b-ae7b65609772/uw187bc_processed.png)

f(x)=4/243(27-x3) for 0<x<3
0 Otherwise
We have to find
a.. P(1<X<2)
b.. E(X)
c.. Third moment of X
