If ther r 4 males& 3 females awardees,in how many ways can they b seated if d male&female take alternate seats

Answer 1

The only way to make sure there aren't two males together (assuming they can only be seated in a single row) is to seat them Male-Female-Male-Female-Male-Female-Male...  Any other configuration will have two males together.
