If $P(A) = 0.25, P(B) = 0.50$ and $P(A \cap B) = 0.14,$ then $P(A \cap \bar{B})$ is equal to

Taking the set of natural numbers as the universal set,write down the complement of the following set:
$A = \{ x : x \text{ is a natural number divisible by } 3 \text{ and } 5 \}$

Taking the set of natural numbers as the universal set,write down the complement of the following set:
$A = \{ x : x \text{ is an even natural number} \}$

If $P(A) = 0.65$ and $P(B) = 0.15$,then $P(\bar{A}) + P(\bar{B}) = $

The number of subsets of $\{1, 2, 3, \ldots, 9\}$ containing at least one odd number is

If $U = \{a, b, c, d, e, f, g, h\}$,find the complement of the set $C = \{a, c, e, g\}$.
