If X is binomial variate with `E(X)=5` and variance 4. The parameters of the distribution are

If X is a binomial variate with mean 6 and variance 2, then the value of P(5leXle7) is

In a binomial distribution the mean is 15 and variance is 10. Then, parameter n is

" If "X" is a binomial variate with "n=6" and "9 p(x=4)=p(x=2)," the parameter "'P'" is "

If X is a poisson variate with P(x=0)=0.8 then the variance of x is

In a binomial distribution, the mean is 4 and variance is 3. Then its mode is

A random variable X has the distribution. Then , variance of the distribution, is

If in a binomial distribution mean is 5 and variance is 4, write the number of trials.

The mean of a binomial distribution is 20, and the standard deviation 4 calculate parameters of the binomial distribution.
