Probabilites regarding 3 coin tosses

If we flip any coin three times here are all the possible outcomes.
\(\displaystyle \begin{array}{*{20}{c}}
H&H&H\\
H&H&T\\
H&T&H\\
H&T&T\\
T&H&H\\
T&H&T\\
T&T&H\\
T&T&T
\end{array}\)
Now YOU do some work. Answer each of the questions and post the results.
If you do not then do not expect any further help.

Thanks, and I am new here, I started posting before I even read the rules, but I am working on it and I will write back! :)

1. =0.125
2.=0.125
Now, the other two, I am still struggling, I thought it could be 0.25, but it ain't. Any help there?
 
Each sequence is equiprobable. But some sequences have the same total number of heads and tails as other sequences.
