If P (A) = 2/11, P(B) =3/11, and P(C) =4/11, what can you say about P(A or B or C) when P(A and B and C)=0?

    Prob(AorBorC)=Prob(A)+Prob(B)+ Prob(C)-Prob(AandB)-Prob(BandC)-Prob(AandC) + Prob (AandBandC).

    so. cranking it out...check closely...

    Prob(AorBorC)=2/11+ 3/11+ 4/11 -
    2/11*3/11 - 3/11 * 4/11 - 4/11*2/22 + 0

    81/121 -24/121= 57/121

    check that.
