In a matrix of transition probabilities (where i equals the row number and j equals the column number),

A) each number represents the conditional probability of being in state j in the next period given that it is currently in the state of i.
B) each number represents the probability that if something is in state i, it will go to state j in the next period.
C) the number in row 3, column 3 represents the probability that something will remain in state 3 from one period to the next.
D) the probabilities are usually determined empirically.
E) All of the above
