You can put this solution on YOUR website! I'll take shot at it, but you might want to get
a 2nd opinion
Since the treasurer must be a lady, there are
60 different ways that office can be filled
Since the Secretary must be a man, there are
40 ways that office can be filled.
There are different ways
that the 2 offices can be held
-------------------------
Once the Treasurer and Secretary offices have
been filled, there are
people left to fill President and Vice-President
There are different ways to fill
these 2 offices ( M or F doesn't matter )
-------------------------
The 4 offices can then be filled in different ways.
( I lost calculator, you can finish )
