Bayes theorem

Alright,

So, I got an answer and my friend got a totally different answer... so be a tie breaker.

p(d)=4% p(e|d)= 95% p(e|d')=5% p(e'|d')=95% and, p(e'|d)=5%

I worked it out and got .33%, then I re-did it and got .44% then tried again and got .04%....


heeeelllpppp.

Re: Bayes theo

Hello, FreaKariDunk!

Are there typos?
The numbers don't tally up.

Re: Bayes theo

P(d|e)=p(e|d)*p(d)/p(e|d)*p(d) + p(d')* p(e|d')


soooo.... .95*.04/.04*.95 + .96* .05


then .44 = 44%

right?
