For Which type of random variable does the Px x exist A Disc

For Which type of random variable does the P(x =x) exist?

A. Discrete

B. Neither Continuous nor Discrete

C. Continous

D. Both Continuous and Discrete

Solution

Probabilty at a particular point exist only in discrete distribution not in continuous distribution. That is for continuous distribution

P(X=x)=0

So option A is correct.
