推 JuanMaestrow: If X follows continuous distribution then P(X=x) 02/10 07:47
→ JuanMaestrow: =0. if X is finite space like Bernoulli(p) then 02/10 07:47
→ JuanMaestrow: P(X=1)=p and P(X=0)=1-p. Since the questions sa 02/10 07:47
→ JuanMaestrow: ys X is any random variable, the answer is false 02/10 07:47
→ JuanMaestrow: because that’s not always the case. 02/10 07:47
