I know this section of the forum is more for Sims than formulas.. but I was really hoping that someone out there may have already created something for this..

I'm looking for a formula that will accept deck size and number of terminal actions, and output the probability of any given terminal colliding with another. Has anyone attempted such a thing? For example I've seen percentages quoted for the chances of two terminals colliding during turns 3-5.. but I've never seen the formula used to calculate that. I can definitely accept that some error is going to be necessary, as the reshuffle will technically add more cards to the 'deck' than were there originally. Thanks to anyone who can point me in the right direction.
