**MathGuru**, Thursday, October 4, 2012 at 9:18pmHere are some hints:

P(x) must add up to 1. Also, all numerical values for P(x) must be between 0 and 1. These two properties need to be satisfied for these problems to be considered a probability distribution.

I'll let you take it from here. (Here is another hint: only one of these problems fits the criteria.)
