Question

Explain Discrete Probability Distribution.

Answer 1

Discrete random variable: A random variable takes countable number of values is called discrete random variable

Ex: The number of children in a family

The number of patients in a hospital

X=0,1,2,........,n

Discrete Probability Distribution:Let X1,X2,.......Xn be n discrete random variables takes n observations x1,x2,......xn with probabilities p1,p2,......pn(p1+p2+...........+pn =1) then the {Xi; P(Xi); i=1,2,....n)} is called discrete probability distribution.

Ex:Some of the disease probability distribution are

Binomial distribution

Poisson distribution

Geometric distribution
