INCORRECT
Sorry, but the answer you
chose is not correct. To figure this
problem, we must use the formula:
Dn = n!( 1-(1/1!)+(1/2!)-(1/3!)+…+(-1)n(1/n!) )
.
In this problem, n=5 because
there are 5 players or objects. Which makes our calculation look like:
D5 = 5!( 1-(1/1!)+(1/2!)-(1/3!)+(1/4!)-(1/5!)
) = 5!(1/2-1/6+1/120) = 120(44/120) = 44 .
So the correct answer is 44.
