A true-false test has 4 questions. What is the chance of answering all questions correctly by guessing?

1 answer:

5 0

Answer:

Thus, in total, there are 24=16 ways to answer the four questions. Only one of these 16 sequences is correct. Assuming each of these 16 sequences is equally likely to occur (as would result from random guessing), the probability that all four questions are answered correctly is 1/16.
