Question 342639

 There are 7 men and 3 women and we have to choose committee of 5
 
     no. of ways to select 5 from total 10 = 10C5


      now, we have to ignore those groups that have only men 
      
     no. of ways to select 5 person from only 7 men = 7C5


              
         required no. = 10C5 - 7C5 =  252 - 21 = 231
