Question

4. Can the following list represent a complete probability model?

P(2) = 1/12
P(3) = 2/3
P(4) = 1/4

Answer 1

Yes

Explanation:

A complete probability model should sum up the probability to 1

by adding them up, you will find the sum as 1/12 + 8/12 + 3/12 = 12/12

So, they can be a complete probability model with 3 outcomes "2", "3" & "4"
