Can you pls explain the solution?

Out of the 6 available places , at any time these two persons can occupy only 2 places at a time irrespective of the orientation. I mean if there are so consecutive space named as 1,2,3,4,5, and 6. Then that can occupy either 1and 4 out of the six places or 2and 5 or 3 and 6. So at any particular instant they have the probability of 2 places our of six places.
This yields 1/3 or .33.

I have tried to explain in my way I understood the problem.

In case you need much clarification pls let me know.
