comment A question on matching points in the plane
@ZubinMukerjee: sure I can agree with that sentiment. But I am intentionally not describing what I did as my approaches thus far have led nowhere. I believe this is a difficult problem but if someone can offer any insight I will be very thankful (in particular, when you generalize from 5 to $n$ and from 3 to $k$.)

comment Why is $1/4$ the probability of hitting 6, starting in 0?
In any. If it goes to the left it can never hit 6. It can go to right on the first try, or loop once then go to the right, two loops go to right etc.
