Question

In a quiz each question has 4 choices, one of them being correct . A student knows the answer,guesses or copies the answer. A student guesses the answer. What is the probability that his answer is correct.

Answer 1

1/4

Explanation:

Given : The total number of choices in each question = 4

Number of correct answers =1

We know that $\text{Probability}=\dfrac{\text{No. of favorable outcomes}}{\text{Total outcomes}}$

If student guesses the answer is correct , then the probability that his answer is correct = $\dfrac{\text{No. of correct answer}}{\text{Total number of choices}}$

=  $\dfrac{1}{4}$

Hence, the correct answer =  $\dfrac{1}{4}$
