The answer is 10/32=5/16.
\n" ); document.write( "Here's how.
\n" ); document.write( "At each step the choice is either heads or tails.
\n" ); document.write( "First toss, H or T.
\n" ); document.write( "Second toss, HH HT TH TT (example:first toss was H, second could be H or T and so on)
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "continue this way until you make a table with all possible values beginning with HHHHH and ending with TTTTT.
\n" ); document.write( "H H H H H
\n" ); document.write( "H H H H T
\n" ); document.write( "H H H T H
\n" ); document.write( "H H H T T
\n" ); document.write( "H H T H H
\n" ); document.write( "H H T H T
\n" ); document.write( "H H T T H
\n" ); document.write( "H H T T T
\n" ); document.write( "H T H H H
\n" ); document.write( "H T H H T
\n" ); document.write( "H T H T H
\n" ); document.write( "H T H T T
\n" ); document.write( "H T T H H
\n" ); document.write( "H T T H T
\n" ); document.write( "H T T T H
\n" ); document.write( "H T T T T
\n" ); document.write( "T H H H H
\n" ); document.write( "T H H H T
\n" ); document.write( "T H H T H
\n" ); document.write( "T H H T T
\n" ); document.write( "T H T H H
\n" ); document.write( "T H T H T
\n" ); document.write( "T H T T H
\n" ); document.write( "T H T T T
\n" ); document.write( "T T H H H
\n" ); document.write( "T T H H T
\n" ); document.write( "T T H T H
\n" ); document.write( "T T H T T

\n" ); document.write( "5 heads - \"1%2F32\"
\n" ); document.write( "4 heads - \"5%2F32\"
\n" ); document.write( "3 heads - \"10%2F32\"
