The wave function $\psi$ of a certain system is the linear combination $\psi=\sqrt{\frac{1}{4}} \psi_{1}+\sqrt{\frac{3}{4}} \psi_{2}$ where $\psi_{1}$ and $\psi_{2}$ are energy eigen functions with eigen values (non-degenerate) $\mathrm{E}_{1}$ and $\mathrm{E}_{2}$ respectively. What is the probability that the system energy will be observed to be $\mathrm{E}_{1}$ ?
(a)$\sqrt{\frac{3}{16}}$
(b)$\frac{3}{4}$
(c)$\frac{1}{4}$
(d)$\sqrt{\frac{1}{4}}$
