Given the transition matrix `P=([0,.42,.58],[0,1,0],[.54,0,.46])` we are asked to find `P^2` . (This is the matrix after 2 repetitions of the experiment.)

`P^2=P*P=([.3132,.42,.2668],[0,1,0],[.2404,.2268,.5248])`

(Just use matrix multiplication or technology.)

The entries in this matrix give the probabilities of transitioning from one state to another after 2 repetitions of the experiment.

Thus the probability of transitioning from state 3 to state 2 originally was 0, but after another repetition it is .2268.
