You have provided a probability density function (PDF) \( f(x) = c(4x - 2x^2) \) for \( 0 < x < 2 \), and you are tasked with solving two questions:

### (a) Determine the value of \( c \).

To solve for \( c \), we need to ensure that the total probability integrates to 1, as required for all probability density functions (PDFs). Thus, we need to solve:

\[
\int_0^2 c(4x - 2x^2) \, dx = 1
\]

### (b) Find \( P\left(\frac{1}{2} < X < \frac{3}{2}\right) \).

After determining the value of \( c \), we can calculate the probability within the specified interval:

\[
P\left(\frac{1}{2} < X < \frac{3}{2}\right) = \int_{\frac{1}{2}}^{\frac{3}{2}} c(4x - 2x^2) \, dx
\]

Let me proceed by calculating the value of \( c \) first.

The value of \( c \) is \( \frac{3}{8} \).

Next, I'll calculate the probability \( P\left(\frac{1}{2} < X < \frac{3}{2}\right) \) using the same function. Let's proceed with that step.

It seems like I can’t do more advanced data analysis right now. Please try again later.

However, you can still manually calculate the probability by substituting \( c = \frac{3}{8} \) into the PDF and integrating over the interval \( \left[\frac{1}{2}, \frac{3}{2}\right] \):

\[
P\left(\frac{1}{2} < X < \frac{3}{2}\right) = \int_{\frac{1}{2}}^{\frac{3}{2}} \frac{3}{8}(4x - 2x^2) \, dx
\]

This will give you the desired probability.

Would you like to explore this further or have any additional questions?

### Follow-up questions:
1. How do we perform integration for probability density functions?
2. What is the importance of the constant \( c \) in probability density functions?
3. How do we interpret probabilities in continuous distributions?
4. Can we find the cumulative distribution function (CDF) for this PDF?
5. What are the common properties of probability density functions?

**Tip:** Always ensure that the total integral of a probability density function over its domain equals 1, confirming it's valid.
