Hey! Why would someone downvote this? It's a legitimate question. Remember, each of us was once new here too. To answer your question, abcd_z, the open thread is a thread, posted weekly now, that is intended for posting all these minor or slightly off topic things. Basically, if it's worth saying, but not worth its own post (even in Discussion), then it goes there. Your post is the kind of thing that definitely should be in the Open Thread rather than in Discussion.
Solve for: The probability that she's over me given that she didn't answer my call.
Estimated probabilities:
The probability that she'd miss my call given that she was over me: 90%
The probability that she's over me: 30%
The probability that she'd miss my call given she was not over me. 10%
(P(over me|missed call)= P(missed call|over me)*P(over me)) / (P(missed call|over me)*P(over me)+P(Missed call|Not over me)*P(Not over me))
P(O|M)=(P(M|O)*P(O))/(P(M|O)*P(O)+P(M|N)*P(N))
P(O|M)=(.9*.3)/((.9*.3)+(.1*.7))
P(O|M)=(.27)/(.27)+(.07)) = .27/.34 = .794
Probability that she's over me given that she didn't answer the phone: 79.4%
TT_TT
EDIT: Something I've noticed here is that people are pointing to the chosen priors and saying that they seem unrealistic.
In our 3-year relationship, she almost never missed my calls, or if she did she would contact me back as soon as she realized that she missed my call. In the current situation, she did no such thing.
EDIT2: Yes, we broke up. Sorry I didn't make that clear.
