If the probability distribution of a random variable X is given as

$x_i$	0	1	2	3
$p_i$	$2k^2$	$k^2$	$3k^2$	$k$

Then the mean of X is

A discrete random variable X has the following probability distribution :

X:	0	1	2	3	4	5
P(X):	b	3b	5b	3b	4b	6b

The value of b is :

Match the LIST-I with LIST-II

	LIST-I		LIST-II
A.	In a binomial distribution, if $n = 16$, $p = 0.75$, then the mean is	I.	$4$
B.	In a binomial distribution, if $n = 25$, $p = \dfrac{1}{5}$, then variance is	II.	$32$
C.	In a binomial distribution, the mean is 8 and the variance is 6, then the number of trials is	III.	$18$
D.	If the mean and variance of a binomial distribution are 6 and 4 respectively, then the number of trials is	IV.	$12$
