\mathrm{P(A)= P\left(E_1\right) \cdot P\left(A / E_1\right)+P\left(E_2\right) \cdot P\left(A E_2\right)}
Where \mathrm{A= \{\text { Employed Person\}; } }

\mathrm{ E_1= \left \{\text { Selected Person in Men } \right \}};
\mathrm{E_2=\left \{ E_2= \text { Selected Person in Women } \right \}}

\mathrm{ P= 0.5 \times 0.8+0.5 \times 0.5}
     \mathrm{ = 0.4+0.25}

\mathrm{ P=0.65}
