In your case you end up with 1 in 6.965 x 10^66.
I'd be careful about tapping people on the shoulder, calling them john, and chancing a pick at their ball bags.
which in lay terms is 1 in a billion billion billion or more billions required?

Good signature btw :-)
What you've got there is a percentage, like the chance of flipping a coin and getting a head is 0.5
What Threaded is suggesting is taking the reciprocal, ie. 1/your answer. In the coin example that gives you 2, so it means you have a 1 in 2 chance.
