EPTThe answer isnt that obvious. Depending on the exact meaning it can have 2 answers. If were specificly looking at a game where always one of the games was zvz the answer would be 1/5. If we happen to stumble upon a game of zvz and then look at the other game the answer would be 1/3. Either way, not really that usefull to discuss over and over again.

Played zerg at least once, so the possible outcomes are: ZZ ZT ZP TZ PZ Then "other game was zerg" if we take it as game 1 is the "other" game then the probability is 3/5. If you take it as game 2 is the "other" game then it is also 3/5. There is no 3/5 in here. The "other" refers to the game that is not already confirmed as zerg, not a random pick out of the two games. This is a simple failing of English comprehension on your part. | ||

"The "other" refers to the game that is not already confirmed as zerg" So you are not CONFIRMING that one game is already zerg? Then it is 1/3 It is not a failing of English comprehension on my part, it is ambiguity and interpretation of the meaning of "OTHER". Hence why you wont ever see a real math problem worded using this use of "OTHER" due to the ambiguity. | ||

explanation: there are 5 scenarios in witch at least one game was as Zerg: (first T, second Z) , (first P, second Z) , (first Z, second Z) , (first Z, second T) , (first Z, second P) in only one of those the other game is as Zerg as well, so the odds are 1 in 5 Q.E.D | ||

"OTHER" Other than what? Other than the game already confirmed as zerg? IT IS INCREDIBLY AMBIGUOUS. Tell me please what the "OTHER" refers to and I will give you the probability. OP has given no indication of the starting point as to where the "OTHER" is based.

That is your interpretation of the word other. Given that interpretation, yes 1/5 is correct. | ||

"At least one game is zerg, what is the other?" How can you interpret other as anything else? I don't understand. There are only two elements in this question. One has been identified and the asker is now asking for the other. Where is the ambiguity? | ||

"at least one game" is not a starting position for a reference of the word OTHER. If you're implying that at least one game is zerg, given that you choose that game which is zerg what is the probability of the other game being zerg. THEN IT WOULD BE 1/3. It is incredibly ambiguous. At least one game is zerg, you're choose that game and then looking at the other game to that one zerg game? The "at least one zerg" condition is already fulfilled so there is no dependence on that constraint for the other game that you choose hence it being 1/3. Answer this: Both games are zerg. What is the "OTHER" game. | ||

I played as Zerg at least once. What is the probability that my other game was as Zerg as well? You see that "as well" at the end? Or do you just randomly pick what words of the OP you want to read and completely disregard those you don't like? | ||

By that logic it is 1/3 because you've chosen the zerg game, from that starting point you're asking what the OTHER game will be. You've already got at least 1 zerg game so that condition is fulfilled so your possibilities for the OTHER game are Z, T, P = 0.33333333333333333333333333333333333 | ||

In other words, "What's the probability of me ending up getting Zerg twice in two games if I'm a Random player, given the knowledge that I'll get Zerg at least once (doesn't have to be the first game)." ZT ZP ZZ TZ PZ 1 out of 5 Zerg choices give me double Zerg. Therefore, 1/5. QED ^^ | ||

We're arguing semantics on an ambiguous statement. Both games have already occurred. You are arguing the position that only the first game has been determined and only look at the probability for the 2nd game. He could even show you the replay of a zerg game, but you don't know whether it was the first or the second that he played. | ||

it cannot be 1/3 cuz there's three races and zerg has already been played so it's either 1/4 or 1/5 but 1/4 is a pair number and there's 3 races, which is unpair so it's gotta be 1/5 not the most efficient nor accurate thinking process, but i earn success nevertheless  and i'm an arts student! | ||

He defines one game as vs. Zerg and then asks for the probability of the other game while referencing to the Zerg game. | ||

That is a different question to "What is the probability of the other game being zerg" though. Answering the question you stated, then yes you are correct with your math. | ||
