The Basics of Counting
Let $\mathrm{A}=\left\{x_{1}, x_{2}, \ldots \ldots \ldots, x_{7}\right\}$ and $\mathrm{B}=\left\{y_{1}, y_{2}, y_{3}\right\}$ be two sets containing seven and three distinct elements respectively. Then the total number of functions $\mathrm{f}: \mathrm{A} \rightarrow \mathrm{B}$ that are onto, if there exist exactly three elements $x$ in A such that $\mathrm{f}(x)=y_{2}$, is equal to : (a) $14 \cdot{ }^{7} \mathrm{C}_{3}$ (b) $16 .{ }^{7} \mathrm{C}_{3}$ (c) $14{ }^{7} \mathrm{C}_{2}$ (d) $12 .{ }^{7} \mathrm{C}_{2}$
