2 .42
3 .09
4 .01
Is this a valid probability distribution? If not, why?
Is this a valid probability distribution? If not, why?
a. It is not a valid probability distribution because ∑f(x) > 1.
b. It is not a valid probability distribution because ∑f(x) < 1.
c. It is not a valid probability distribution because f(O) ≠ 0.
d. Yes, it is a valid probability distribution.
Answer: a. It is not a valid probability distribution because ∑f(x) > 1.
