Exactly 4 actors try out for the 4 parts in a play. If each actor can perform any one part and no one will perform more than one part, how many different assignments of actors are possible?
24 assigments.
Take four parts (1,2,3,4)
RJSA RJAS RASJ RAJS RSAJ RSJA (6 combos)
That’s for R playing role 1. If S,J,or A play role one, you would get another 6 combinations. 6×4=24 combos.
Hope this helps!
