#### Answer

Dependent, $\frac{58}{9900}.$

#### Work Step by Step

Two events are dependent, if the outcome of one effects the outcome of the other. Here the events are dependent, because the selected senator reduces the opportunities for the next selection. $P(A \cap B)=P(A)\cdot P(B|A)$. Hence $P(A \cap B)=\frac{58}{100}\cdot\frac{1}{99}=\frac{58}{9900}.$
