I need help with this one. Please be as detailed as possible so I can understand the way to do it

**Problem 4:** Two independent random variables \( x_1 \) and \( x_2 \) are both uniformly distributed between 9 and 11. Find the probability density function (pdf) of \( y_1 = \frac{x_1 x_2}{x_1 + x_2} \). **Hint:** Introduce the dummy variable \( y_2 = x_2 \) and use the approach of two functions of two variables.
