**Frequency Distributions** In Exercises 5 and 6, complete the table to form the frequency distribution of the random variable *x*. Then construct a bar graph to represent the result.

**Bar Code** A computer randomly selects a three-digit bar code. Each digit can be 0 or 1, and *x* is the number of 1’s in the bar code.

To determine

**To calculate:** The frequency distribution of the random variable *x* which is defined as the number of 1’s in the three-digit bar code with each digit being 0 or 1 by completing the table and represent the result by a bar graph.

**Given Information:**

A three-digit bar code is randomly selected by a computer with each digit can be 0 or 1. The random variable *x* is defined as the number of 1’s in the bar code.

**Formula used:**

The number of occurrence of a specific value of *x* is called the frequency distribution.

**Calculation:**

Consider that a three-digit bar code is randomly selected by a computer with each digit can be 0 or 1.

Define the random variable *x* as the number of 1’s in the bar code.

For a three-digit bar code selected randomly by a computer with digit as either 0 or 1, there will be 7 possible outcomes for the three-digit bar code. So, the sample space is:

Thus, the sample space is

As the random variable *x* is defined as the number of 1’s in the bar code, the possible values of number of occurrence of 1’s in all the outcomes are
