If the random variable `1`follows a Poisson distribution with mean `3` then `P(X=0)` is

A random variable X has Poisson distribution with mean 2 .Then P(X>= 2) equals

A randam variable X has Poisson's distribution with mean 2. Then , P(X)gt 1.5) is equal to

A random variable X has poisson distribution with mean 2. Then P(x>1.5) is equal to (A) (2)/(e^(2))(B)0(C)1-(3)/(e^(2))(D)(3)/(e^(2))

If a random variable X follows binomial distribution with mean 3 and variance 3/2, find P(Xlt=5)dot

A discrete random variable X is said to follow the Poisson distribution with parameter m ge 0 if its p. m. f. is given by P(X = x) = (e^(-m) m^x)/x , x = 0,1,2,.... True or False.

A random variable X has poisson's distribution with mean 3. Then find the value of P(Xgt2.5) .

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

Suppose a random variable X follows the binomial distribution with parameters n and p, where 0

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
