Q. 1 D4.4( 7 Votes )

State which of the following are not the probability distributions of a random variable. Give reasons for your answer.

Answer :

Given: A given table with values for X and P(X).

As we know the sum of all the probabilities in a probability distribution of a random variable must be one.



Hence the sum of probabilities of given table = 0.3 + 0.2 + 0.4 + 0.1 + 0.05


= 1.05 ≠ 1


Hence, the given table is not the probability distributions of a random variable.
