Question

the probability of guessing the correct answer to a certain question is P divided by 12 if the probability of not guessing the correct answer to the same question is 3 / 4 then find the value of p

Answer 1

here we can see that
the probability of guessing the correct answer=P/12 (case 1)
and
the probability of guessing the wrong answer is 3/4 (case 2)
so now
no examining case 1 and case 2
the probability of getting a correct answer is 1/4
so atq
$\frac{1}{4} = \frac{p}{12}$
LCM of 4 and 12= 12
