No
Which concept of probability? :D
Mine is ~1.0, just like my probability that Newton's Laws make sense.
18 nines maybe?
Since the concept is one of subjective expectation/prediction, and "makes sense" is ALSO subjective evaluation, it's currently 1.0 - it makes sense to me. I may someday change enough that it doesn't make sense, but you didn't ask my probability of whether it'll continue to make sense, you only asked about now.
I'm disappointed by the downvotes and by the answers. I don't see any problem with this question, and the concept it points at is useful to think about.
