Good job you were not my TA:-). I think he is referring to higher dimensional random variables (aka joint distibutions of 1-d RVs. Then this makes sense too: > > I have no idea what is meant by E(A,B). > You can measure expectation on any event, can't you? Expectation is usually defined on RVs (wih a suitably 'integrable measure') (thus it is rather tortuous to give a meaning to 'the expectation of the colour of a random Smartie(M&M)'). So yes, as Michael said, I shall consult colleagues actively teaching in this area and produce a suggested CD containg the current stuff and these types of notation. chris _______________________________________________ Om3 mailing list [email protected] http://openmath.org/mailman/listinfo/om3
