Suppose the transition matrix for a Markov process is State A State B State A State B 1 1] 0 1-P р р 9 where 0 < p < 1. So, for example, if the system is in state A at time 0 then the probability of being in state B at time 1 is p. Webbp(A or B) = p(A) + p(B) - p(A and B). The logic behind this formula is that when p(A) and p(B) are added, the occasions on which A and B both occur are counted twice. To adjust … WebbWhen A and B are independent, P (A and B) = P (A) * P (B); but when A and B are dependent, things get a little complicated, and the formula (also known as Bayes Rule) is P (A and B) = P (A B) * P (B). chelmsford to stansted airport
