Question

"a test has 5 multiple choice questions with four choices with one correct answer each. if we just randomly guess on each of the 5 questions, what is the probability that you get at least 1 questions correct?"

Answer 1

1 out if 20 you would get right

There is 5 questions 4 answers to pick from so 5 times 4 is 20

Then they said what is the probability of only getting one answer right

So the answer would be 1 out of 20 1/20
