You can put this solution on YOUR website! You want to make five-letter codes that use the letters A, F, E, R, and M without repeating any letter. What is the probability that a randomly chosen code starts with M and ends with E?
------
Pattern:: M---E
# of ways to succeed:: 1*3*2*1*1 = 6
-------
# of random 5-letter codes using those letters without repetition: 5! = 120
------
P(condition) = 6/120 = 1/20
