0.02% (roughly 5,000/1) for 2 of us to get it in 2
Spoiler:
I would not say lucky. Most people would want an E and O in there, and E last and O 2nd or 3rd was most logical. I initially was looking at CLONE, as L and N are great letters, but the N was gone. I thought of CLOSE but foolishly dismissed it because S does not hit much out of the 1st spot. So I went with CREDO, even though E and O are flipflopped, but R and D could give great info, as could the E and O obv, even in wrong spots.
Anyway, just saying there are lucky guesses and logical guesses that hit. I think CLOSE is logical pick and not lucky...
