CM_Tutor, thankyou so much for the solution!! and thankyou everyone for the input also!!! a massive help!!
i think i was quite confused by the P(subscript)y which is now agreed to be a misprint and instead P*y but now that clears it all up
This question is giving me a headache starting from part a, I really dont even understand what theyre asking for...
Would anyone be able to please help?
Thankyou!
