just for fun and cool uses for Perl, here the math for the first column
DB<29> $h = 5
DB<30> sub A_and_B { bk($n-2,$h-2) / bk($n,$h) }
DB<31> sub bk { my ($n,$k) = @_; fac($n)/(fac($k)*fac($n-$k)) }
DB<32> sub fac { my ($n) =@_; my $f=1; $f*=$_ for 2..$n; $f}
DB<33> printf ( "%i %0.3f\n", $n=$_, A_and_B ) for 6..15
