Question 463108: suppose that there are four jobs to be allocated among seven workers. if only one worker is to be assigned to each job, and any of the workers is able to do any of the jobs, how many different possible allocations can be made?
my confusion is either to solve for permutation or combination.

In this particular problem you solve for combination because in every set of 4 workers, there are 24 possible combinations (4*3*2*1).
Possible allocations = 7*6*5*4
= 840
Use permutation when there is no need to assign each worker with a particular job.
