Work Step by Step

If A and B are dependent events, then P(A and B) = P(A)*P(B given that A has occurred) E: a coconut-filled chocolate followed by a caramel-filled chocolate. A: A coconut-filled chocolate B: A caramel-filled chocolate given that a coconut-filled chocolate is selected first. P(A) = $\frac{5}{30}$ P(B) =$\frac{10}{29}$ P(E) = $\frac{5}{30}$ .$\frac{10}{29}$ P(E)=$\frac{5}{87}$
