Brad Doe works for a packaging company. One day, he received four separate orders and accidentally mixed up the addresses, so he applied the address labels at random.
What is the probability that exactly three packages were correctly labeled?
Ans: 3/64 = 0.0469 =4.69%
First we select 3 packages out of four in 4C3 ways.
Probability that these are correctly labelled is 1/4 for each package.
