Update: Added spoiler tags

Update 2: Looking now at the OP's much more verbose code, I wonder if mine is not too concise, especially if the aim is to convince someone who doubts the actual odds.

Anyway, it was enough to convince me! :)

        I i could give them to you, i probably would.

        But i'm just a humble Pilgrim, working in the Department Of Bugsniffing. My hope is, that, one day, i'll be promoted to Friar. If i'm very lucky, i might even get my own desk.

    The problem with your "concise" solution is that it's unclear whether your program matches the problem description. If you don't care about the latter, here's an even more concise one: 
    use 5.010;
say "Please wait while I run a simulation ....";
sleep 5;
say "Elves have wrapped a billion parcels, calling FedEx ....";
sleep 10;
say "Not switching wins 33.3% of the time";
say "Switching wins 66.7% of the time";
