A famous discussion between two mathematicians on the existence of god, i believe Euler (i could be wrong) was the recipient of such an argument:
other mathematician: what do you say is the probability that god exists?
Euler: I believe 1/1,000,000,000,000,000
other mathematician: well what is the potential benefit from believing in god if you die?
Euler: well if you are right, then i will receive eternal bliss.
Other mathematician: well, if we simply calculate the expected outcome, we have 1/1,000,000,000,000,000 times infinity which means you would have an outcome benefit of infinity. while if God doesn't exist, and one doesn't believe anyways, then there is no lost.
