# Thread: Probability and Correlation

1. ## Probability and Correlation

Hello,
I have just started learning these things, would really appreciate any help on this.
There are 4 nodes in a network (say A,B,C,D)and each node has certain failure probabilities( P(af),P(bf),P(cf),P(df) ).
Then,I have this 4x4 correlation Matrix which contains the correlation coefficients for every pair of nodes. How can I calculate P(af|bf) or P(af|bf cf df)?

Thanks
