[c] \[10<\begin{matrix} 3m \\ 7w \\ \end{matrix}3\] Women can be selected in \[^{7}{{C}_{3}}\]ways and can be paired with 3 men in 3! Ways. Remaining 4 women can be grouped into two couples in \[4!/(2!\,\cdot 2!\,\,\cdot 2!)=3.\] Therefore, total \[{{=}^{7}}{{C}_{3}}\,.\,3!\,.\,3=630\].You need to login to perform this action.
