Answer :
A distribution is said to represent a probability distribution if it satisfies these two conditions:
• P(x)≥0, the ,probability of a random variable x cannot be negative,, that is, it must be a number between 0 and 1.
[tex]0\leq P(x)\leq1[/tex]• The ,sum of all the probabilities in the distribution must equal 1,. That is:
[tex]\sum_{i=1}^nP(x_i)=1[/tex]If any of these conditions fail in a distribution, it does not represent a probability distribution.
