@slh This is fiendish.
@slh There is no answer. right?
There being two identical answers is against the rules, but if we suppose there's only one answer, a, b, c or d, then you choosing at random makes your choice independent of the question, so it's 25% chance. The question doesn't imply you have to choose at random, but you'll have to choose a or d, which gives you a 50% chance of winning, better than random. Now I'm interested in your reasonning :)
A random one-in-four is 25%: correct-answer-1.
Since two answers are '25%', the chance of randomly selecting correct-answer-1 is actually 50%: correct-answer-2.
Since there is only one answer with '50%', the chance of selecting it randomly is 25%: correct-answer-3.
Since two answers are '25%', the chance of randomly selecting correct-answer-3 is actually 50%: correct-answer-4...
Reasoning hangs on definition of 'correct' I guess 😄
Eu responderia 50% (C).
O motivo para minha resposta é que das 4 (ABCD) possibilidades, 2 estão inválida (BD). Sobrando só (AC). E 1 certa em 2 possibilidades reais é 50% de chance (Escolho C).
@slh I love it! Anyone knows whether it's real or if it's was just edited?
