S is the sample space and $A, B$ are two events of a random experiment. Match the items of List $A$ with the items of List B

$$ \text { List A } $$		$$ \text { List B } $$
I	$A, B$ are mutually exclusive events	a.	$$ P(A \cap B)=P(B)-P(\bar{A}) $$
II	$$ A, B \text { are independent events } $$	b.	$$ P(A) \leq P(B) $$
III	$$ A \cap B=A $$	c.	$$ P\left(\frac{\bar{A}}{B}\right)=1-P(A) $$
IV	$$ A \cup B=S $$	d.	$$ P(A \cup B)=P(A)+P(B) $$
		e.	$$ P(A)+P(B)=2 $$

$P(A \mid A \cap B)+P(B \mid A \cap B)=$

Two digits are selected at random from the digits 1 through 9. If their sum is even, then the probability that both are odd, is

A, B and C are mutually exclusive and exhaustive events of a random experiment and $E$ is an event that occurs in conjunction with one of the events $\mathrm{A}, \mathrm{B}$ and $C$. The conditional probabilities of $E$ given the happening of $A, \mathrm{~B}$ and C are respectively $0.6,0.3$ and 0.1. If $P(A)=0.30$ and $P(B)=0.50$, then $P(C / E)=$
