The number of times the New York appeared while pulling the quarter is =10.

The sample space is =25.

The probablity of pulling a New York quaredet is,


\begin{gathered} P=(10)/(25) \\ =0.4 \end{gathered}

The number of time Amber pulled New York Quarter can be estimated as,


\begin{gathered} N=P*300 \\ =0.4*300 \\ =120 \end{gathered}

Thus, option (C) is the correct solution.
