An urn contains n m balls, of which n are red and m are black. they are withdrawn from the urn, one at a time and without replacement. let x be the number of red balls removed before the first black ball is chosen. we are interested in determining e[x]. to obtain this quantity, number the red balls from 1 to n. now define the random variables xi , i
