A: Water Pollution is present B: A Water Sample was found polluted C: water is safe for fishing Assume P(A)= 0.30. P(B | A)= 0.75, P(B | A')=0.20, P(C | AnB)= 0.20, P(C | A'nB)=0.15, P(C | AnB')=0.80, and P(C | A'nB')=0.90 Find P(AnBnC) ii. Find P (B'nC) ili. Find P(C) iv . Find the probability that the water pollution is present given that the water is safe for fishing and the sample water was not found polluted
