$\frac{1}{12}$
You do not replace the coins, so the events are dependent. 2 of the 9 coins are pennies: P(penny)=$\frac{2}{9}$ 3 of the 8 remaining coins is a quarter: P(nickel after penny)=$\frac{3}{8}$ P(penny then nickel)=P(penny) $\times$ P(nickel after penny) P(penny then nickel)=$\frac{2}{9}$ $\times$ $\frac{3}{8}$ P(penny then nickel)=$\frac{1}{12}$
