Question

Q5-The probability of guessing the correct answer to a certain question is x/2.1f probability of not
guessing the correct answer is 2 /3 then find x.​

Answer 1

Answer:

Here, probability of guessing the correct answer = x / 2

And probability of not guessing the correct answer = 2 / 3

Now, x / 2 + 2 / 3 = 1

⇒ 3x + 4 = 6

⇒ 3x = 2

⇒ x = 2 / 3
