I think we have to break it down into every possible case regarding the numbers of men and women on the committee.

 

\(\text{If there are $m$ men and $w$ women on the committee we have}\\ n_{m,w}=\dbinom{5}{m}\dbinom{6}{w} \text{ ways to select the committee from the members}\\~\\ N= \sum \limits_{m=1}^3\sum \limits_{w=2}^4 \dbinom{5}{m}\dbinom{6}{w}=1250\)
