You should also notice that we used the product rule to calculate the probability of P H and Q T and also the probability of P T and Q H, before we summed them. WebBy this definition, we have t0 = t3 = 0. To find t1 and t2, we use the law of total probability with recursion as before. For example, if X0 = 1, then after one step, we have X1 = 0 or X1 = 2. Thus, we can write t1 = 1 + 1 3t0 + 2 3t2 = 1 + 2 3t2. Similarly, we can write t2 = 1 + 1 2t1 + 1 2t3 = 1 + 1 2t1. semley auctioneers shaftesbury
