I've concluded that if I have cards 1 2 3 2 and someone asks how many recurred 2 found in cards? I would say 2 and not 1 that's logic !

but in real life we aren't dealing with that thing which in real life we understand the term of "recur" that's after the first attempt happen which means for my questions the answer would be 1 because the second appearance of number 2 actually the recurred ..

I'm fine with this, so what approach should I take? in real life or math's logic?! in real life the term recur means after the first occurrence how many times it happen again? (not including the first occur)

any help?! thanks
