Question
Is the following distribution a probability distribution
(x, P(X)) = (-2,1.23); (-1, 0.15) ; (0, -1.20); (1, 0.52); (2, 0.30)
There are five ordered pairs: X values and their probabilities for example P(1) = 0.52.
X, -2, -1, 0, 1, 2
P(X), 1.23, 0.15, -1.20, 0.52, 0.30
True or False?

there are 5 pairs, but they are not all probabilities. Why not?
