Grimmett & Welsh, in "Probability, An Introduction" state "A slightly different but morally equivalent definition of a discrete random variable is a function X : Omega -> R such that there exists a countable subset S =E2=8A=86 R with P(X =E2=88=88 S) = =3D 1." --=20 Bob Newell Honolulu, Hawai`i - Via GNU/Linux/Emacs/Gnus/BBDB
