Counting probabilityi need some help counting probability using Bayes theorem Last edited by zxcvbnm123 (20130725 21:57:20) #2 20130725 05:27:40

Re: Counting probabilitysorry can elaborate more? i just assume that i understand the theory and guess the number. if i am wrong please tell me in more details. #4 20130725 05:59:55
Re: Counting probabilityThe detector has just detect a message as being spam. what is the probability that the message is actually not a spam message? Last edited by SteveB (20130725 06:22:57) #5 20130725 06:09:25
Re: Counting probabilitythe question is pretty confusing for me too. but i think what i need to look for is P(not spam given that the message is flagged as spam). #6 20130725 06:35:00
Re: Counting probabilityI am wondering whether it might help to draw a diagram similar to this adapting where needed #7 20130725 06:42:22
Re: Counting probability(0.10*0.11 + 0.9*0.89) Last edited by SteveB (20130725 07:37:32) #8 20130725 15:05:37
Re: Counting probabilityI think the answer might be: (0.099 / (0.089 + 0.099) Last edited by SteveB (20130725 15:09:28)
