Hey MOTU fans, I just started attending graduate classes to get my M.A. in psychology, and my research professor gave the class an extra credit probability question. I am terrible at stats/math, hence my love for psyc .
Here is the question below:
Brent Brunner worked at a packaging company. One day, Brent received four separate orders and accidently mixed up the addresses, so he applied the labels at random. What is the probability that exactly three packages were correctly labelled?
