|q⟩ Bad Qubits

Multiple choice
A two-qubit state has (unnormalized) amplitudes 00+01+10|00\rangle + |01\rangle + |10\rangle, each scaled by 1/31/\sqrt{3}. Forming the 2x2 coefficient matrix MM (rows = A, cols = B), the squared Schmidt coefficients are the eigenvalues of G=MMTG = M M^T, namely about 0.87270.8727 and 0.12730.1273. What is the entanglement entropy S=λlog2(λ)S = -\sum \lambda \log_2(\lambda), in bits?
