I have a question on determing the composition of a state of a system of composed of only two eigenvectors, the question is displayed below:

I initially assumed that the ket v was given by:

[tex]|v>=a|\omega_{1}>+b|\omega_{2}>[/tex]

Where 'a' and 'b' are constants which will determine the probability of either state. So we know the probability of the eigenvalues of ket v are given by the coefficients a and b in the equation:

[tex]\mid <v|\hat{\Omega}|v>\mid^{2}[/tex]

Where for the probability of attaining the eigenvalue ω(1) we have equation:

[tex]\frac{1}{4}=a^{4}[/tex]

Though I'm not sure this is correct, it implies

[tex]a=\frac{1}{\sqrt{2}}\: ,\: b=\sqrt{\frac{\sqrt{3}}{2}}[/tex]

I think I have made a mistake on my third equation...

Thanks for any help,
