Has any full chess game from opening move to final 49th or 79th move ever happened twice? What is the probability? How often expected if ever?

Wow interesting I was reading Nunn on the unlikelihood of exactly repeating with every move a complex ending if youre not a computer, including move order but copying from memory all 60 moves if your opponent also did all 59 of theirs exactly didnt occur to me! Thanks!

I can assure you that this game has happened more than once. 

As far as I know, this is the longest forced draw, as any deviations are bad for black after he plays the Berlin.

I am sure that the two-move Fools' Mate and the four-move Scholars' Mate has been successfully completed thousands of times before.

 

The longer the moves (eg 49 or 79), the less likely repetition will occur (and I believe there is only a very tiny handful of exactly repeating moves occurring in multiple games, but I have not personally come across one yet).

the answer is probably yes, if the two players cooperate to play the exact same moves of another game (which I think has happened before)

There is  common trap in the stonewall attack that I have played probably 20 time, but IIRC it's at move 20 or earlier
