Consider the following continuous Joint PDF.(Please show how to solve, The use of TI84 plus functions ARE allowed please use them and show in the steps as well, iI really appreciate it thabk you)
f(x,y)=K*x/2 y
In K1
a. Sketch the region where the PDF lies.
b. Find the value of the constant K that makes this a valid joint probability density function
c. Find the marginal density function y.
d. Find the Expectation Y .1/y and 1
