Answer:
The correct option is (c) :4
Given: The probability of guessing the correct answer to certain question= x/12
The probability of not guessing the correct answer for the same question=2/3
The sum of all the probabilities of all possible outcomes of experiment is 1.
P(Event) +1 (not an Event)=1
P(guessing the correct answer)+P(Not guessing the correct answer) =1
x/12+2/3=1
x/12-1-2/3
x/12-(3-2)/3
x/12=1/3
3x=12
x=12/3
x=4
Hence the value of x is 4.
Hope it's helpful.
