标题: LOS 8.g. Total Prob / Unconditional Prob [打印本页] 作者: rosemary2011 时间: 2011-7-13 14:52 标题: LOS 8.g. Total Prob / Unconditional Prob
I don't quite get the concept of this. I've got a feeling this is a real simple concept but that I've over complicated in my head and now can't untangle it. Perhaps someone can explain.
Text says Total Prob rule...explains the unconditional prob of an event in terms of probabilities that are conditional upon other events.
But I see this as a contradiction, as I understand unconditional probability as the prob of an event regardless of past or future occurance of other events. So therefore how can Unconditional Prob be explained in terms of probs that are conditional upon other events?作者: Mechanic 时间: 2011-7-13 14:52
Hey Superinconsistent, I always use diagrams or probability trees for these questions. They're great for making the answers look logical. Sorry I can't be of any more help. It's Saturday night and I have a few beers.作者: Kiakaha 时间: 2011-7-13 14:52
Thanks Soddy. Hey us two saps posting on AF on a Sat nite - and such a fine city to be out boozing in. Time for a beer I think...作者: leadcfa 时间: 2011-7-13 14:52
Hey beatthecfa, that example does clear the concept up somewhat (I re-read it several times I'll admit). Thanks - and good job in answering this and the other Quants questions posted today.作者: rgonzalez 时间: 2011-7-13 14:52
Good answer beatthecfa.
Superinconsistent, are you going to the CFA Ireland candidates night in Dicey's on the 27th?作者: shootingstar 时间: 2011-7-13 14:52
Hey Soddy. That's actually the first I've heard of it. I guess I should read back over my emails in case I overlooked it. I probably would go. Assume you're going? Karen too?作者: soddy1979 时间: 2011-7-13 14:52
I'm going. Karen knows about it but I don't know if she is going - she hasn't said. Email me at cfasod at gma!l and i'll send you on a copy of the invite if you haven't got it.作者: joemoran 时间: 2011-7-13 14:52
