Answer:

The possible values for X is: {0,1,2,3,....,12}

Yes, it is a discrete random variable.

Step-by-step explanation:

Consider the provided information.

We need to determine whether the variable is discrete or not.

Discrete variables are which can only take on a finite number of values.

Let the variable X be the number of unbroken eggs in a randomly chosen standard egg carton.

In a standard egg carton we can put 12 eggs.

Therefore, the possible values for X is: {0,1,2,3,....,12}

The number of unbroken eggs (X) can take infinite values, thus by the above definition it is a discrete random variable.
