##### Exercise3

Determine whether the following statements are true or false and provide a justification of your response.

Every stochastic matrix has a steady-state vector.

If \(A\) is a stochastic matrix, then any Markov chain defined by \(A\) converges to a steady-state vector.

If \(A\) is a stochastic matrix, then \(\lambda=1\) is an eigenvalue and all the other eigenvalues satisfy \(|\lambda| \lt 1\text{.}\)

A positive stochastic matrix has a unique steady-state vector.

If \(A\) is an invertible stochastic matrix, then so is \(A^{-1}\text{.}\)
