A beg contains 4 white and 6 red balls. Four balls are drawn at random, then match the probability of the numbers of white balls drawn. Where P(E) denotes the probability of an event E.

Then Match List-I with List-II

LIST-I		LIST-II
A.	P (no white ball)	I.	$\frac{8}{21}$
B.	P (all white balls)	II.	$\frac{1}{14}$
C.	P (one white ball)	III.	$\frac{6}{14}$
D.	P (two white balls)	IV.	$\frac{1}{210}$

Choose the correct answer from the options given below:

A card is picked at random from a pack of 52 playing cards. If the picked card is a queen, then probability of card to be of spade type also, is

If A, B and C are three independent events such that P(A)=P(B)=P(C)=x, then P(at least two of A, B, C occur) =

Bag I contains 4 red and 3 black balls and bag II contains 6 red and 5 black balls. One ball is drawn at random from one of the bags, the probability that it is a red ball, is

A random variable X has the following probability distribution:

Then the value of $\frac{k}{4}$ is:

If A and B are two events such that $P(A) \neq 0$, $P(B) \neq 1$ and $P(\bar{A}/\bar{B}) = \frac{1-k}{P(\bar{B})}$, then the value of $k$ is

For the following probability distribution :

$E(X^2)$ is equal to :
