Then there is NO way of showing a percentage for possibility of God raising Christ from the dead...
Correct.
There are several ways to estimate the probability of a dead person coming alive again. The simplest way is to pick a random selection of the people who have died and count how many of them came alive again. If we take everybody who died in the 20th century (OK not a random sample, but it will do for illustrative purposes), and count how many were resurrected, we get a probability of 0/5.5 billonish. Even accepting all of the reports of resurrection at face value, it's still probably millions to one against.
Of course, if God is involved, he could choose to resurrect just a handful of people in the whole of history in which case the sample size needs to be enormous to get anything other than zero. My methodology above would be equivalent to selecting 100 people who bought lottery tickets yesterday, checking if any of them win the jackpot on Saturday and, when they don't, concluding that it is impossible to win the lottery jackpot.
I could try calculating the probability another way, just as with the lottery we can figure out the probability of winning the jackpot through permutations and combinations. I could look at the probability in quantum mechanical terms of the particles of the dead person spontaneously jumping into a state where they constitute a living person. This is possible but astronomically unlikely. There again, if God exists, he could nudge the particles into the correct configuration.
Unfortunately, we can't assume God exists for two reasons. Firstly, the death and resurrection of Jesus is one of Alan's Flakey Five arguments for God. If God id necessary to make the resurrection credible as well, we have a circular argument. Secondly, it's impossible to calculate probability if somebody is loading the dice. If you want to use probability at all, you have to assume God does not exist - or at least is not influencing the experiments.
