The variance of the random variable `X` having the following distribution is `{:(X=x:,-2,-1,0,1,2),(P(X=x):,(1)/(6),(1)/(6),(1)/(3),(1)/(6),(1)/(6)):}`

A random variable X has the following probability distribution: [[X=x,0,1,2,3], [P(X=x),(1)/(8),(1)/(2),(1)/(4),k]]

Select and write the correct answer from the given alternatives in each of the following : A random variable X has the following probability distribution : {:(X=x,-2,-1,0,1,2,3),(P(x),0.1,0.1,0.2,0.2,0.3,0.1):} Then E(x) = ………

Find the variance of the following distribution {:(,x_(i),2,3,11),(,f(x_(i)),1/3,1/2,1/6):}

Find the variance and standard deviation of the random variable X whose probability distribution is given below : {:(x,0,1,2,3),(P(X=x),1/8,3/8,3/8,1/8):}

The mean and variance of a random variable X having a binomial distribution are 4 and 2 respectively.The P(X=1) is

The mean and variance of the random variable X which follows the following distribution are respectively. X = x:- 1 2 3 4 p( X = x):- 0.1 0.2 0.3 0.4

lim_(x rarr0)((1+x)^((1)/(6))-(1-x)^((1)/(6)))/(x)=(1)/(3)

(2x-1)/(3)+(3x+2)/(2)+7=(1)/(6)+(4x+3)/(6)

(2x-1)/(3)+(3x+2)/(2)+7=(1)/(6)+(4x+3)/(6)
