Answer
Explanation:
Step1: Check probability range
All probabilities $P(X = x)$ must be between 0 and 1. Here, $0.7\geq0$ and $0.7\leq1$, $0.05\geq0$ and $0.05\leq1$, $0.25\geq0$ and $0.25\leq1$.
Step2: Check sum of probabilities
Calculate the sum of probabilities $\sum P(X = x)=0.7 + 0.05+0.25$. $0.7 + 0.05+0.25 = 1$
Answer:
Yes, Since the probabilities lie inclusively between 0 and 1 and the sum of the probabilities is equal to 1.
