$[\begin{array}{c} \frac{1}{2} & \frac{1}{3} & \frac{1}{2} \\ 0 & \frac{1}{3} & \frac{1}{4} \\ \frac{1}{2} & \frac{1}{3} & \frac{1}{4} \end{array}] [\begin{array}{c} \frac{1}{2} \\ \frac{1}{2} \\ 0 \end{array}]$

Step 1

Multiply each row in the first matrix by each column in the second matrix.

$[\begin{array}{c} \frac{1}{2} \cdot \frac{1}{2} + \frac{1}{3} \cdot \frac{1}{2} + \frac{1}{2} \cdot 0 \\ 0 (\frac{1}{2}) + \frac{1}{3} \cdot \frac{1}{2} + \frac{1}{4} \cdot 0 \\ \frac{1}{2} \cdot \frac{1}{2} + \frac{1}{3} \cdot \frac{1}{2} + \frac{1}{4} \cdot 0 \end{array}]$

Step 2

Simplify each element of the matrix by multiplying out all the expressions.

$[\begin{array}{c} \frac{5}{12} \\ \frac{1}{6} \\ \frac{5}{12} \end{array}]$
