Question

Can anyone provide any guidance to this probability problem? I have the answer I just dont know how to get it.

Answer 1

what is P(ABC) if P(A)=P(B)=P( c)=.5, P( A U B)=.55, P(A U C)= .7, P(BC)=.3, and P(ABC) =2P(ABC^(complement))? the answer is .3

Answer 2

i have found that P(AB) = .45 and P(AC)=.3 and i believe i need to do something with those but im not completely sure

Answer 3

I afraid i may just not know a rule or something and i dont even know where i should look so that is all im looking for help with. I have look us all the union and intersection rules and that stuff as well but im not sure how to use them with 3 variables

Answer 4

Did you post this in the Statistics section?

Answer 5

Answer 6

Yes, there is one

Answer 7
