Random Walk

• Run ten trials  with n = 5 and for each trial  report:

Trial  #      Very First  Step      First Edge Reached      Final Direction      Steps
1      left – right      left – right      left – right      
2      left – right      left – right      left – right      
3      left – right      left – right      left – right      
4      left – right      left – right      left – right      
5      left – right      left – right      left – right      
6      left – right      left – right      left – right      
7      left – right      left – right      left – right      
8      left – right      left – right      left – right      
9      left – right      left – right      left – right      
10      left – right      left – right      left – right      

• How often did the direction  of the first step match the final direction  of the walk?



• How often did the first edge reached match the final direction  of the walk?



• What  was the average number of steps required for these ten particular  trials?

What is the assignment and what is your question?  You should not expect that it will be solved for you.  It is against the rules here, and it would also be unfair to yourself as you would miss the chance to learn.  On the other hand, you can get advices here.

Think of the left / right as something like a coin toss.
With a coin, you either get heads, or tails (ignoring the possibility of landing on the edge, of course).

So, I interpret these as two possible directions that can be taken at each decision point.

This documentation page talks about generating "random" numbers with Python:
