You require a numerical probability for a 'universal collapse' event?

How about 'practically nil' [:o] ?

Oh? That's interesting, could you please elaborate further?

....and what do you intend to do with such a numerical probability?

Perhaps the conditions necessary for such an event are more interesting to discuss?

I suspect that in our present state of cosmological knowledge any attempt to predict the likelihood of a big crunch would rely more on the crystal ball than the computer. However, there are some interesting side issues, such as the possibility that any information could pass through a crunch/bang situation into a succeeding universe.

At the moment the best calculations and measurements we have show that the big crunch is very unlikely - the hubble constant is such that the universe will keep expanding and we will end up cold, dark, and lonely.
