SOLUTION: If X={10, 20, 30, 40} and P(10)=0.30, P(20)=0.30, P(30)=0.30, and P(40)=0.30, can distribution of the random variable X be considered a probability distribution?

Question 1077461: If X={10, 20, 30, 40} and P(10)=0.30, P(20)=0.30, P(30)=0.30, and P(40)=0.30, can distribution of the random variable X be considered a probability distribution?

No, because the four given probabilities do not have sum = 1.00

0.30+0.30+0.30+0.30 = 1.20, not 1.00
