Pemdas, you are now arguing against *three* native English speakers who also happen to be experts on this material. Think about it -- when that happens, you are probably the one who's wrong.
Also, in earlier posts we've already noted that
the wording of the question is unnecessarily ambiguous, and that
you should ignore the question -- because the question is not going to contribute anything to your understanding of the test.
in fact -- as we are seeing right here, right now -- this question is currently serving to
decrease your understanding, because you are becoming more and more convinced of a position that is actually invalid.
if you actually want to learn things for the test -- rather than defend an emotional investment in your argument -- then please ignore the wording of this problem, starting right now.

It's not individual probability for each event, otherwise the problem stated simply 'Each lottery has winning chance 50%' and not 'Out of 100 lottery tickets, each having 50% chance'.
those two statements are indistinguishable, except in that the second also specifies the total number of tickets.
for your interpretation to be correct, the wording would have to say something like "...out of 100 lottery tickets,
50 of which are winners".
the current version says "each ticket has a 50% chance of winning" -- so that's what the current version means.
this is not the same as "exactly 50 tickets are winners", so that's the wrong interpretation.
this is the last post i will make on this topic, because there's nothing more to say about it -- but i can tell you with 100.000% confidence that:
* the position of the experts in this thread is correct;
* your current position is incorrect;
* this question is worthless, will cause nothing but confusion, and should be ignored.
