God, I don't get why people get so worked up over this stuff. X_X HAHAHA, nice one! Actually I think mathematics are amazing...when they are used properly. These threads ALWAYS turns into a wording argument. It's frustrating. Like that 1/2*5=? bullshit. There's no right or wrong answer because the wording the problem itself is too ambiguous so people just argue for goddamn ever!! ARHGHH!!! I'm fed up with this bullshit! + Show Spoiler + ye. | ||

So I was playing random today, and I played 2 games of Starcraft 2! I played as Zerg at least once. What is the probability that my other game was as Zerg as well? The way you stated it , you played one game as zerg. The question you ask is what is the chance u play as zerg the 2nd game which is still 1/3. ZzZzZ | ||

Srs bzns note: I thought it was 1/3 as well rather than 1/5. It seems to be very ambiguously worded -- then again, I always sucked at the verbal part of standardized tests.  | ||

so at MOST the chance is 1/3 becuz you asked if you played AS zerg and the choices are Terran, Protoss, and Zerg. Correct me if I'm wrong and explain it better, lol. I want to know  | ||

"My other game" implies that you are only asking about the odds of that one game *given* that you were Zerg in the first game. | ||

You can get zerg 30 times in a row the next game the probability of zerg will still be 1/3 That is unrelated to the question that the OP was asking. He is not saying ``I played my first game today as random and got zerg. What is the probability that I was zerg in the second game, too?''. He is saying ``I played two games today, and I will tell you that I was zerg at least once. Knowing that, what is the probability that I was zerg twice?''. Many of the other posters in the past page or two have had the same misunderstanding. For those of you who will say that I originally said that the problem was ambiguous, I will say that if someone gave me this problem I would first say 1/5, then say, ``but you should be careful about how you word the problem in the future, because...''. The ambiguity in this problem is very close to being nonexistent, and most of the people in this thread missed the actual ambiguity and are actually completely misunderstanding the question. | ||

You said you played as zerg AT LEAST once, so that's saying you played as zerg once, which is the minimum. so at MOST the chance is 1/3 becuz you asked if you played AS zerg and the choices are Terran, Protoss, and Zerg. Correct me if I'm wrong and explain it better, lol. I want to know He's asking what the odds are that he got Zerg BOTH games. The way the question is worded it looks like he's asking what the odds are that he'd get Zerg in a single game. | ||

The way the question is worded it looks like he's asking what the odds are that he'd get Zerg in a single game. Exactly. The way it's worded you can just totally ignore ONE of 2 games, and give the probability of the other gane, which is 1/3. | ||

1/5 would be the answer if the Bnet server tells you that you are about to play two games, and it will make it so that you play zerg at least once. In that case, PZ and ZP would be different, but in this case, they are the same. | ||
