4. An incredibly bored admissions tutor decides to liven up his job. He has three decision
letters intended for three Oxbridge candidates: an offer, a rejection, and a pooled response.
He decides to send each candidate a letter intended for someone else to mess with the
system.
In how many different ways can he send the letters?
A 2
B 4
C 6
D 8
E 11
Can anyone solve this question? I keep getting the same answer and I cannot possibly see how the correct one is true. I shall post the correct answer after a few of you attempt it. Thank you for your help!
