In the above question we have to find the probability of correctly answering the first 2 questions on a multiple choice test if random guesses are made and each question has 3 possible answers.
That is,
The chance of correctly answering a question is 1:3 = 1/3
We have to find the probability of correctly answering the first 2 questions on a multiple choice test
Here, the answering the first 2 questions on a multiple choice test are independent with each other.
Therefore,
The probability of correctly answering the first 2 questions on a multiple choice test are as below
So, the probability of correctly answering the first 2 questions on a multiple choice test are 1/9
Answer :-
