+\ARROW We choose with equal probability the point inside $D$ where the particle walks.\\
 \ARROW With equal probability we choose the next positions and so on until the particle hits the boundary in the point $Q^{\prime}$.\\
-\ARROW We count all trajectories $N((x_1,x_2,x_3,...,x_k)$ that that have passed the point $(x_1,x_2,x_3,...,x_k)$.\\
+\ARROW We count all trajectories $N(x_1,x_2,x_3,...,x_k)$ that that have passed the point $(x_1,x_2,x_3,...,x_k)$.\\
 \ARROW For the point $(x_1,x_2,...,x_k)$ we calculate:
 \begin{align*}
 w(x_1,x_2,...,x_k)=\frac{1}{2k}N(x_1,x_2,...,x_k)\frac{f(Q)}{p(Q)}
 \end{align*}
-\ARROW The above steps we repeat $N$ times.\\

 \ARROW After that we take the arithmetic mean of $w$.
