A true-false test has 8 questions. What is the probability of guessing the correct answer to all of the questions

1 answer

Assuming each question has an equal probability of being guessed correctly, the probability of guessing the correct answer to one question is 1/2 (since there are two possible answers: true or false). Therefore, the probability of guessing all 8 questions correctly is:

(1/2)^8 = 1/256

So the probability of guessing all 8 questions correctly is 1 in 256.
