The probability of answering correctly if you make a random guess is:
P = 1/5 = 0.2
If you make a random guess, then you have no idea of which could (or couldn't) be the correct answer. Thus, all the 5 options have the exact same probability of being the correct one.
From this, the probability of answering correctly the question is given by the quotient between the number of correct answers (we assume is only one) and the total number of options (5).
So the probability is:
P = 1/5 = 0.2
