Question

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 A?

Answer 1

there are 5 letters used for the code.

The probability of A being first the number of A’s which can be picked (1) over the total number of letters that can be picked (5).

The probability of A being first is 1/5

1/5 = 0.2
