Question

On a quiz, there are 5 true-false questions. Wiria guesses on all 5 questions. What is the probability that he gets all 5 questions right?

Answer 1

Since it is a true-false question, there are only 2 possibilities. Either it is true or it is false.


`\text {P(right) = } (1)/(2)`


`\text {P(right for all 5 questions) = } ((1)/(2))^5 = (1)/(32)`
