OKAY !! So i have solved the mystery :P It wasn't letting me sleep :D
Kangkan I am using Bayes theorem and it ill fetch the same answer.
S = { FF,MM,FM}
Let E = first letter from F = {FM,FF}
A= Both are from female = {FF}
B= First female and second male = {FM}
P(A)= 1/3
P(B)= 1/3
P(E/A) = 1, P (E/B)=1
P(A/E)= (1*1/3)/(1*1/3+1*1/3)= 1/2
So, Bayes Theorem gives the same answer on following Ron's method if we use new sample space by kangkan

So thanks Ron & kangkan :D
