Question 1096350: Hi, I am having trouble figuring out how to solve this following problem:
A real estate office has 10 sales agents. Each of four new customers must be assigned an agent.
(a) Find the number of agent arrangements where order is important.
(b) Find the number of agent arrangements where order is not important.
I have considered using methodologies such as assigning a customer name to each sales agent such as assigning customers 1,2,3,4 to agent 1 all the way to 37,38,39,40 to agent 10 and attempting to switch the customers around so that every possible combination is found. I know this is a combination problem, but I do not know how to apply the formula.
