A multiple choice test has 20 questions. Each question has five possible answers, of which one is correct. If a student guesses on every question, find the probability that the student will get exactly 12 correct. Round your answer to four decimal places.

3/25

Step-by-step explanation:

A multiple choice test has 20 questions and each question has five possible answers, of which one is correct.

Therefore, the probability of getting an answer right by guessing is:

1/5

The probability of getting 12 out of 20 correct is therefore the product of the probability of getting each question right and 12/20:

1/5 * 12/20 = 3/25

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an
