Here’s One I Posted At My Home Forum:

This is interesting and absolutely based on a video I am watching, I just thought it might be worth doing it here to see what results we get

Oh yeah, since it’s stats I’m putting it in science.

Two people are tossing coins and recording the whether it goes head or tails, each is looking for a particular sequence:

[list][*]HTH (HEAD - TAILS - HEAD)

[*]HTT (HEAD - TAILS - TAILS)[/list]

Consider the following possibilities:

**A:** The average number of tosses until HTH is larger than the average number of tosses until HTT.

**B:** The average number of tosses until HTH is the same as the average number of tosses until HTT.

**C:** The average number of tosses until HTH is smaller than the average number of tosses until HTT.

Which of the above, in your opinion, is correct and why?

I will give the answer and show the video in a while.
