For any two independent events $E_1$ and $E_2$,$P\{(E_1 \cup E_2) \cap (\bar{E}_1 \cap \bar{E}_2)\}$ is

Let $A$ and $B$ be two sets such that $n(A) = 0.16$,$n(B) = 0.14$,and $n(A \cup B) = 0.25$. Then $n(A \cap B)$ is equal to:

If $X = \{a, b, c, d\}$ and $Y = \{f, b, d, g\},$ find $Y - X$.

The shaded region in the Venn diagram can be represented by which of the following?
