Permutations nPr Calculator

P(n,r)=  n!

(n−r)!  = ?

n (objects) =5

r (sample) =  3

P(n,r)=P(5,3)

=  5! /(5−3)!

= 60

The result shows that Mark can put the 5 pebbles in the 3 fish tanks in 60 different ways, if each fish tank must have at least one pebble.  Using the permutation calculator, the number of ways is calculated to be 60 ways.
