Step 1

Consider, *X* be the random variable that represents the number if adults who feel comfortable in a self-driving vehicle.

Step 2

A probability distribution function must satisfy the following conditions:

- Sum of probabilities must be equal to 1.
- Probabilities must lie between 0 and 1.

Here, conditions required for a probability distribution are satisfied because probabilities are between 0 and 1 and sum of probabilities is equal to 1 which can be shown as:

Step 3

Since, both the conditions for a probability distribution function are sati...
