There are 4 answers for a single question on the exam and only one answer is correct. If a student guesses the answer for this question, what is the probability that the student selects the correct answer? (round to 2 decimal places)

0.25

Step-by-step explanation:

There are 4 answer choices given and only 1 is correct. The other 3 will be incorrect.

To find the probability of getting the right answer, divide the number of correct answers by the total number of answer.

P(correct answer)=correct/total

There is 1 correct answer out of a total of 4 answer.

P(correct answer)=1/4

The question asks us to round to 2 decimal places.

P(correct answer)=0.25

The probability that the student selects the correct answer is 0.25.
