Suppose that all of the outcomes of a random variable are ( a, b, c, d, e), and that P(a) = P(b) = P(c) = P(d) = 1/4, (that is, all outcomes a,.b,c and d each have a 1/4 probability of occurring), and P(e)=0. Define the events A ={a,b}, B={b,c}, C={c,d}, and D={e}. True or false. The events A and D are independent.
