Markov Chains & Long-Run Behavior · Easy problem

A two-state Markov chain has transition matrix $M = \begin{pmatrix} 0.9 & 0.2 \\ 0.1 & 0.8 \end{pmatrix}$, where $M_{ij}$ is the probability of moving to state $i$ from state $j$. The starting distribution is $\mathbf x_0 = \begin{pmatrix} 0.5 \\ 0.5 \end{pmatrix}$. What is the probability of being in state 1 after one step? Express your answer as a decimal.
