Random Walk up and down in the grid
If the walk goes only up and down in the grid that the instructor illustrates, how come he goes horizontally (the second step goes to the cell on the right side), instead of only up and down? I don't understand this. Thanks!
Thank you for your question!
The point here is that you start on the left end and progress to the right. So, after each toss, you move either up or down and then you have to move to the right.
I hope that answers your question! :)
