Answer:

P=20%

Step-by-step explanation:

Let's suppose that each question in the test has one and only one correct answer. This means we have 1 desired outcome out of the total 5 desired outcomes. Therefore:

Probability=#of desired outcomes / #of possible outcomes

or

P=\frac{1 correct}{5 opctions}

P=\frac{1}{5}

P=0.20

P=20%
