Work Step by Step

If A, B and C are dependent events, then P(A and B and C) = P(A)*P(B given that A occurred)*P(C given that A and B occurred) E: three cans of apple juice. A: apple juice B: apple juice given that one has already been selected C: apple juice given that two have already been selected P(A) = $\frac{6}{20}$ P(B) =$\frac{5}{19}$ P(C) = $\frac{4}{18}$ P(E) = $\frac{6}{20}$ .$\frac{5}{19}$. $\frac{4}{18}$ P(E)=$\frac{1}{57}$
