Your use of the "and rule" is incorrect. What is true is that if P and Q are independent events, then the probability that P and Q happen in that order is P(P)P(Q). The probability that Q and P happen in that order is P(Q)P(P). The probability that P and Q happen in either order is P(P)P(Q)+ P(Q)P(P)= 2P(P)P(Q)
