odds of flipping fair coin heads 74X is 1 in 1.88x10^22
so yeah B

This has certainly nothing to do with math. Infact you can't say any of the possible answers are true using math.
Of course it could be you were doing a Laplace experiment and dumbcows estimate for the probability for that outcome would be true. BUT any other 75-sequence/outcome has exactly the same low probability. Well yes, the probability for the number of heads is different. But the observation could also come from the fact, that the experiment is not Laplace. i.e. you flip the coin always in nearly the same way, and thus you should get almost everytime the same result.

Nowhereman, chill.  It's just basic probability.  There's no reason to throw around Laplace transformations and the like.  Most basic math questions have no place in the real world anyway :D
