Assuming that there are only two possible answers (true or false) for each question and the guess is completely random, the probability of guessing the correct answer for any one question is 1/2 or 0.5.
Therefore, the probability of guessing the correct answer for all eight questions is:
0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 = 0.00390625
or approximately 0.39%.
So, the probability of guessing all 8 questions correctly is very low.
A true of false test has 8 questions what is the probability of guessing the correct answers to all of the questions
