In Exercises 1–6, calculate the relative frequency

Eight hundred adults are polled, and 640 of them support universal health-care coverage. *E* is the event that an adult supports universal health-care coverage. [**HinT:** See Example 1.]

To determine

**To calculate:** The relative frequency for the event that an adult supports universal health-care coverage where eight hundred adults are polled and 640 of them support universal health. Also, *E* is the event that an adult supports universal health-care coverage.

**Given Information:**

Eight hundred adults are polled and 640 of them support universal health. *E* is the event that an adult supports universal health-care coverage.

**Formula used:**

When an experiment is performed *N* times, the relative frequency or estimated probability *E* is the fraction of times *E* occurs.

It is given by,

**Calculation:**

Consider the event that an adult supports universal health-care coverage to be *E*
