What do you want to find,
P(E_1)=0.25, P(E_2)=0.75, P(FlE_1)=0.05. P(FlE_2)=0.12. P(E_2lF). Ok I'm looking for an area or space between both. As for the text book no good example is close to this one. Ok so 0.25*0.75=.1875, and 0.05*0.12=.006. Now is the hard part what do I do next. I would like to say 0.188 is the answer but I'm not sure. List of possible answers are -
1. 0.188
2. 0.878
3. 0.060
4.0.370
Thanks for any help given.
