Solution:-
We know that the sum of the probability of any event is 1
Therefore the probability of guessing the correct answer + not guessing the correct answer = 1
x/3 + x/5
(5x + 3x)/15
8x/15
x = 15/8
So, the value of x is 15/8
Now, we cross the value of x by substituting the value of x.
x/3 + x/5 = 1
15/8 ÷ 3 + 15/8 ÷ 5 = 1
(15/8) × (1/3) + (15/8) × (1/5) = 1
5/8 + 3/8 = 1
8/8 = 1
1 = 1
L.H.S. = R.H.S.
