Question

The probability of guessing the correct answer to a certain question is x/2 If the probabilityof not guessing the correct answer is ²/3
, then find the value of x.​

Answer 1

Answer:

Step-by-step explanation:

The probability of guessing the correct answer to a certain question = x/2.

→The probability of not guessing the correct answer =1−x/2

1−x/2= 2/3.

→x/2=1−2/3=1/3

Hence x= 2/3
