Three balls are numbered 1, 2, 3 and placed in a bag. Consider the following experiment: two balls are chosen randomly without replacement from this bag. Let X¡ and X2 denote the number of the first and second ball, respectively. Define Y = |X1 – X2|. This experiment is repeated 50 times, the result of the i-th round is denoted by Y;. (a) Determine E[Y;] and Var(Y;).
