Answer
$\frac{2}{21}$
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: Two Democrats.
A: A Democrat
B: A Democrat given that one has already been selected
P(A) = $\frac{5}{15}$
P(B) =$\frac{4}{14}$
P(E) = $\frac{5}{15}$ .$\frac{4}{14}$
P(E)=$\frac{2}{21}$
