Any one to help me about random distribution and probability

A random distribution is a capacity that partners the plausible result of an examination. 

Flipping two coins is the best case to be considered for this irregular dispersion. 

There are four conceivable results where H remains for heads and T remains for tails. 

{HH,TT,HT,TH} 

The likelihood of an irregular variable to happen is characterized as P(X)=x, 

For eg. Give us a chance to consider likelihood of two heads as result when two coins are flipped 

Discover the likelihood the you get two heads. 

So X=2, 

In the above circulation ,i.e., {HH,TT,HT,TH} two heads happen just once in 4 times. 

So the likelihood that you get two heads when two coins are flipped is ¼ 

So P(X=2) = 1/4 

There are two sorts of arbitrary factors: discrete factors and constant irregular factors. 

Discrete Random Variables: 

The word discrete means partitioned and person. In this manner discrete irregular factors are those that interpretation of whole number esteems as it were. They never incorporate divisions or decimals. 

Continuos Random factors: 

These are correct inverse to discrete irregular vairables i.e., they incorporate parts and decimals.
