A shopkeeper wants to check the average number of cars sold per call. Past record of sales is shown below:

Sale of cars (Units)	0	1	2	3
Probabilities	$\frac{1}{6}$	$\frac{1}{2}$	$\frac{3}{10}$	$\frac{1}{30}$

The expected number of cars sold is :

If the probability distribution of X is :

X	2	3	4	5	6
P(X)	1/15	2/15	3/15	4/15	5/15

Then variance is equal to :

Match List - I with list- II

List-I	List - II
A. the probability distribution is applied for discrete random variable	normal distribution
B. A normal distribution is symmetric about	standard deviation
C. this probability distribution is applied for continuous random variable	mean
D. the shape of normal curve depend upon	Poisson distribution
