    2-d uniform distribution.

    Can somebody xplain to me how to find probability density equation of a function which is uniform over (-3,3) on x-axis n uniform over (-1,4) on Y-axis. Its a 2 dimensional probability density function.

    The area of the rectangle you want for support of the pdf is 6\times 5=30, so the pdf is:

    f(x,y)=\begin{cases} \frac{1}{30} & x \in (-3,3) \times (-1,4)\\0 & {\rm{otherwise}}\end{cases}
