1   6!   ways to list pres candidates   x  4! ways to list VPs  x  5!   to list Sec candidates x 3! for treas


    that is   6!  x 4! x 5! x 3!    =...........    (You can do the number crunch...HINT:I get 12 million -something)


2   Less than 500 means only 4 choices for the first position   x   5  choices for second position x 5 choices for third position=

      4 x 5 x 5 = 100 possible combos total    if it ends in 2 or 4 it will be even    2or 4 out of 5  is 2/5    2/5 x 100 = 40 possibilities for even


3  3 ways to choose lineman      

        leaves 9 people to fill 3 positions         3   x   9c3 = 252 posssibilities


4     9 p 4  = 3024    ( I think  cheeky)
