Three research departments have 10,9, and 7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done?

Respuesta :

Order matters if you are picking a person as a delegate and another as alternate.

no. of ways = (10*9) (9*8) (7*6) = 272160

Therefore, there are 272160 ways for the procedure to be done.
