In the following distribution, which one is not continuous distribution?                                    [         ]

A) Normal distribution

B) Exponential distribution

C) Poisson Distribution

D) Uniform Distribution   

Solution

In the following distribution, which one is not continuous distribution?

A) Normal distribution :

Normal distribution is continous distribution with range of the variable is -infinity to +infinity.

B) Exponential distribution :

Exponential distribution is a continous distribution with range of variable is [0 , infinity)

D) Uniform Distribution :

Uniform distribution is a continous distribution with range of variable is [a,b]

In all three cases the variable take all possible values in that interval.

C) Poisson Distribution :

Poisson distribution is not a continous distribution because range of variable is 0,1,2,..............

Poisson variable take particular values that is 0 or 1 or 2 , or ....................

Therefore Poisson variable is not a continous random variable.

It is discrete random variable.

Option c) is correct.
