There are $n$ observations and all of them are negative numbers. The ascending order of these observations is $x_1, x_2, \ldots . x_n$. If the signs of the first term and last term in that order are changed, then the range of the data is
A bag contains 3 white and 6 red balls. Four balls are drawn at a time randomly. Then, the probability of getting at least two red balls is
$A$ and $B$ are two independent events $P(A)=\frac{2}{5}, P(B)=\frac{1}{3}$.
Match the following :
| $$ \text { List I } $$ |
$$ \text { List II } $$ |
||
|---|---|---|---|
| (A) | $\quad P(\bar{A} \cup B)$ | I. | $$ \frac{11}{15} $$ |
| (B) | $P\left(\frac{A}{\bar{B}}\right)$ | II. | $$ \frac{3}{5} $$ |
| (C) | $P(A \cup B)$ | III. | $$ \frac{2}{3} $$ |
| (D) | $p\left(\frac{\bar{B}}{A}\right)$ | IV. | $$ \frac{2}{5} $$ |
| V. | $$ \frac{1}{3} $$ |

The correct match is
Two players $A$ and $B$ are alternately throwing a coin and a die together. $A$ player who first throws head and 6 wins the game. If $A$ starts the game, then the probability that $B$ wins the game is
