You do not replace the coins, so the events are dependent: P(nickel)=$\frac{1}{9}$-1 of the 9 coins are dimes- P(nickel after nickel)=$\frac{0}{8}$=0 -0 of the 8 remaining coins are nickels- Probability: P(nickel then nickel)=P(nickel) $\times$ P(nickel after nickel) P(nickel then nickel)=$\frac{1}{9}$ $\times$ 0 P(nickel then nickel)=0
