    Number of Possible Orders




    In a regional spelling bee, the 8 finalists consist of 3 boys and 5 girls. Find the number of sample points in the sample space S for the number of possible orders at the conclusion of the contest for:
    a) all 8 finalist.
    b) the first 3 positions.

    My solutions:
    a) 8! = 40,320 sample points.
    b) 8!/(8-3)! = 336 sample points.
    Is this correct?

    Yes that looks good to me
    I don't have emotions and sometimes that makes me very sad.
