If `X` is a Poisson variate such that `P(X=3)=P(X=2)`, then `P(X=4)=`

If X is a poisson variable such that 2P(X=0)+P(X=2)=2P(X=1) then E(X)=

If X is a random poisson variate such that E(X^2)=6 then E(X)=

" If "x" is a Poisson variate such that "P(x=0)=0.1" ,"P(x=2)=0.2" then the parameter "lambda" is "

If X has a poisson distribution such that P(x=2)=(2)/(3)P(x=1) then P(x=3) is

If X has a Poisson distribution such that P(x=2)=2/3 P(x=1) then find the value of P(x=3)

If a random variable X has a poisson distribution such that P(X=1)=P(X=2), its mean and variance are

If X follows Poisson distribution such that P (X = 1) = 0.4 and P (X = 2) = 0.2, Then find the value of m

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

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