Joe, Megan, and Santana are salespeople. Their sales manager has 21 accounts and must assign seven accounts to each of them. In how many ways can this be done?

116,280 ways

Step-by-step explanation:

The number of ways of assigning the accounts to each of the salesperson is computed by combination

Number of ways = n combination r = n! / (n-r) ! r!

n = 21, r = 7

Number of ways = 21 combination 7 = 21! / (21-7) !7! = 21!/14!7! = 116,280 ways
