Evolutionists, statistically speaking, what is the probability of abiogenesis happening by random forces?

What kind of life was it? Was it similar to the simplest living thing today? So if the simplest living thing were to have begun by chance without any intelligent design, what was the probability of it happening? One mathmatician said chances would be 1 in 10 with 40,000 zeros. Agree or Disagree. If you disagree, then name your statistics and in what scientific journal, magazine etc was it published etc or how you figured it. Is abiogenesis a hypothesis or theory or fact?
