00:01
So for part a, we want to know what the 6th entry represents.
00:04
Well, the 6th entry is here in the bottom right corner.
00:10
So that tells us it represents the probability of starting in state 2 as we are in the second column and ending in state 2 since it is in the second row.
00:20
So that means part a, the 6th 7 is telling us the probability of starting in 2 and going to 2.
00:30
Now for part b, we want to know what the zero represents.
00:35
Well, we know that the zero is in the top left entry.
00:41
Well, so this means that we are starting in the first state and ending in the first state.
00:46
So the zero is the probability that we start in state 1 and we end in state 1.
00:52
And that's going to be our answer to part b.
00:55
Now, in part c, our question is, if we are in state 1, what's the probability that we're going to be in state one in the next spot? well, to do that, we look, okay, the state one column, and we want to see what the probability entry when we are going to state one on the next step.
01:17
So it's this entry again in the top left corner...
