From Isaac Asimov's The Robots of Dawn:
"I imagine that a mental freeze-out through positronic drift might have a probability of 1 in 1o^12; that by accidental pattern-building 1 in 10^100. That is just an estimate, but a reasonable one. The difference is greater than that between a single electron and the entire Universe--and it is in favor of the positronic shift."
Goold ole' Isaac.
