If a student answered 4 out of 5 questions correctly, how did this student do? How do you know?
Sladkaya [172]

Answer:

Percentage Calculator: 4 is what percent of 5? = 80. What is the probability of getting 5 multiple-choice questions answered correctly, if for each question the probability of answering it correctly is 1/3.

Step-by-step explanation:

If there were just one question, then the probability of guessing correctly would be 1/3. Since all the answers are independent (the answer to one question has no bearing on the answers to the others), then this is the case with each question, so the chances of guessing all answers correctly is 1/3 × 1/3 × 1/3 = 1/27.
