Choose at random a young adult aged 19 to 22 years. Ask their age and where they live (with their parents, in their own place, or in some other place such as a college dormitory). Here is the probability model for the 12 possible answers: Age in Year 19 20 21 22 Lives with Parents 0.12 0.12 0.14 0.12 Own Place 0.02 0.08 0.09 0.08 Other 0.06 0.06 0.05

Why is this a legitimate discrete probability model?
- Because every person falls into exactly one category, the probabilities are all between 0 and 1, and they add up to 1.
- Because the probabilities are all between 0 and 1 and they add up to 1
- Because every person falls into one interval and the probabilities add up to 1.
- Because every person falls into one or more category and the probabilities are all between 0 and 1.
- None of the above
