Arithmetic of random variables:: Transcript

adding constants to random variables multiplying random variables by constants and adding two random variables together AP Statistics B pp 37374 1 Pp 37374 are just plain hard I dont like the way they are written. RANDOM VARIABLES Definition usually denoted as X or Y or even Z and it is th e numerical outcome of a random process Example random process The number of heads in 10 tosses of a coin Example The number 5 rating Expected Value.
