brother .. i think there is some problem with the question could you please check it
tanvika056:
yesss it is 2/3........Sister
then i will give answer .....
p(correct answer)=x/2 = P(e) p(incorrect answer)=2/3 = P(e').. now P(e) + P(e') =1......
x/2 + 2/3 = 1
(3x + 4)/6 = 1
3x + 4 = 6
3x =2
x =2/3
i think ..
tq for the answer

solu:- the probability of any no. is 0 & 1 .
so, x=1/2
0.5
so, x=1/2
