The next test will consist of five questions.

Question

Each question will be multiple choice, with 4 possible solutions listed for each question. What is the probability of an individual correctly answering every question by guessing?

Answer 1

Guadalupe:

There is a 1/4 probability of correctly guessing the right answer on a question.

There are 5 questions each with the same probability of getting the right answer.

So we are looking for Probability(get answer 1 right) and Probability (get answer 2 right) and Probability (get answer 3 right) and Probability (get answer 4 right) and Probability (get answer 5 right)

= (1/4)*(1/4)*(1/4)*(1/4)*(1/4) = 1/4⁵
