Step-by-step explanation:
Discrete Probability Distribution
A discrete distribution can be identified because it only exists for certain values of x and not in between them. The graph of a discrete probability distribution should not be a continuous line, but a limited amount of points or a bar-shaped graph.
a. To numerically verify this is a discrete probability distribution, it's enough to sum the individual probabilities for each value of x. It should sum 1.

b. The graph of the probability distribution is shown in the image below. Its shape is close to the bell curve but skewed (not symmetric) to the left
