Hi,

Mary has 'seven' decorative vases to arrange on a shelf. 

How many different arrangements are possible? 7! = 7*6*5*4*3*2*1 = 5040(calculator)



Probability is much like every discipline in Mathematics (Algebra, for

example, has operations or formulas that work best in particular situations

or 'types of problems', as you put it so well)

 n! operation works with these types.
