Let probability of guessing the correct answer be P(E)
and let, probability of not guessing the correct answer be P(E).
We know that the sum of all probabilities of an vent is 1.
i.e.,P(E)+P(E
₁)+.................+P(Eₓ)=1
ATQ,
x/2=P(E) and x/3=P(E₁)
So, P(E)+P(E₁)=1
x/2+x/3=1
(3x+2x)/6=1
5x=6
x=6/5
