For this case, we have by definition, the calculation of probabilities:

$probability = \frac {number\ of \favorable\ cases} {number\ of\ possible\ cases}$

We have 5 possible answers, and we have only one favorable case, that is, only one correct option among the 5 possible answers.

So, we have:

$Probability = \frac {1} {5} = 0.2$

Answer:

0.2
