4. Two jointly normal random variables defined by the vector V: [XY]" have zero means and a joint pdf that can be specified as: [xx (x,y) 2-K117= - VTX 11 where K is the covariance matrix given by K = ETVV). 1f xy(x,y) (a) Determine the components of the covariance matrix K. (b) What is the correlation coefficient between X and Y ? 10 STEPS TO SUCCESS K IG: @entrepreneurshipfacts 1. Try 2. Try again 3. Try once more 4. Try a little differently 5. Try it again tomorrow 6. Try and ask for help 7. Try to find someone who has done it 8. Try to fix what is not working 9. Try to expand what is working 10. Just keep trying until you succeed 4.
