Determine the values of c so that the following functions represent joint probability distributions of the random variables X and Y : (a) f(x, y)=cxy, forx =1 ,2,3; y =1 ,2,3; (b) f(x, y)=c|x−y|, forx = −2,0,2; y = −2,3.

The joint probility density will be c = 1/36

The joint probability distribution will be c = 1/15

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

360/29
