. THE VARIANCE OF THE RANDOM VARIABLE X WHICH FOLLOWS UNIFORM DISTRIBUTION (6,12) IS

The first four moments of a distribution about x = 4 are 1, 4, 10, 45. the mean is

A R.V X has a uniform distribution over (-3,3), then P(X < 2) is

If X follows binomial with the parameter (3,1/3) and Y follow binomial with the parameter (5,1/3). Then the mean of X+Y is

A R.V X has a uniform distribution over (0,3),then P(X<2).

Let X be a random variable with Var[X] = 1. Find Var (2-3X).

Let X be a random variable with E[X] = 1. Find E (2-3X).

The first four moments of a distribution about x = 4 are 1, 4, 10, 45. Find the Variance

A die is cast untill 6 appear. The probability of getting the success at 3rd attempt is

If X is the random variable with mean 3 and variance 4. Then X follow Binomial distribution.
