It is more idiomatic (and often simpler) to use Perl-style rather than C-style loops.

Yes, but it won't work if the numbers are too large for integers and have to use floating point.    Then only C style loops will work.

my @collect = map 0, 0 .. NUM_TOSSES;

Why are you initializing @collect with NUM_TOSSES + 1 elements?

The idiomatic way to initialize @collect with NUM_TOSSES elements is usually:

my @collect = ( 0 ) x NUM_TOSSES;
for ($i = 0; $i < $numTosses+1; $i++) { foreach my $tailsCt ( 0 .. NUM_TOSSES )

You have an off-by-one error, it should be:

foreach my $tailsCt ( 0 .. NUM_TOSSES - 1 )

Update: oops, I misread the original code.
