Question

A multiple choice test has 5 possible answers. Find the probability of answering all the questions correctly

Answer 1

The answer is 1/5

Explanation:

You have the probability of getting 1/5 correct.

Answer 2

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
