The total number of possible ways of selection is given by,

\mathrm{ ^1^0C_3=\frac{10!}{\left ( 3! \right )\left ( 7! \right )}}

\mathrm{ ^1^0C_3=\frac{\left ( 10\times 9\times 8 \right )}{\left (3\times 2\times 1 \right )}}

\mathrm{ ^1^0C_3=120}

Therefore, the number of possible ways of selection is 120.
