$x$ and $y$ are the arithmetic means of the runs of two batsmen $A$ and $B$ in 10 innings respectively and $\sigma_A, \sigma_B$ are the standard deviations of their runs in them. If batsman $A$ is more consistent than $B$, then he is also a higher run scorer only when
A
$0<\frac{\sigma_A}{\sigma_B}<\frac{\bar{x}}{\bar{y}}, \frac{\bar{x}}{\bar{y}}>1$
B
$\frac{\bar{x}}{\bar{y}}>\frac{\sigma_A}{\sigma_B}>1$
C
$\frac{\bar{x}}{\bar{y}}<\frac{\sigma_A}{\sigma_B}<1$
D
$\frac{x}{\bar{y}}>1,1 \leq \frac{\bar{x}}{\bar{y}}<\frac{\sigma_A}{\sigma_B}$

$$
\text { List A }
$$
$$
\text { List B }
$$
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. $$
