Suppose three out of every four trucks on the road are followed by a car, while only one out of every five cars is followed by a truck. What fraction of vehicles on the road are trucks?

I form a markov chain as followed:

$\displaystyle \[ \left( \begin{array}{ccc}

0.25 & 0.75 \\

0.20 & 0.80

\end{array} \right)\]$

Then find the limiting probabilities $\displaystyle \pi_{track}$ and I got 0.2105.

Am I right?
