Question

A manuscript is sent to a typing firm consisting of typists A, B, and C. If it is typed by A, then the number of errors made is a Poisson random variable with mean 2.6
if typed by B, then the number of errors is a Poisson random variable with mean 3
and if typed by C, then it is a Poisson random variable with mean 3.4. Let X denote the number of errors in the typed manuscript. Assume that each typist is equally likely to do the work. (a) Find E[X]. (b) Find Var(X). Sep 15 2014 06:32 AM
