joint probability density function over the range

Question

Question

Determine the value of c that makes the function f(x,y) = cxy a joint probability density function over the range 0<x<3 and 0<y<x.

Answer 1

Answer #1

this needsto be solved for c. ajoint probability must add up to 1.

=(c/2)

=(c/2)3⁴/4 =1 or

c=8/3⁴ =8/81
