**Answer:**

The probability that the three drivers would wear seat belts is 0.5

**Step-by-step explanation:**

**Given**

Percentage of drivers using seat belt = 80%

Number of drivers pulled over = 3

**Required**

Probability that all three drivers wore seat belt

First, the probability that a driver would wear seat belt has to be calculated.

Let's represent that with P(D)

P(D) is equivalent to the percentage of drivers using seat belt

%

Let the probability that the three drivers would wear seat belts be represented as P(All).

P(All) is calculated as thus;

<em>**(Probability that the first driver would wear seat belt) and (Probability that the second driver would wear seat belt) and (Probability that the first driver would wear seat belt).**</em>

<em></em>

<em>**Mathematically, this means**</em>

Substitute

--- Approximated

**Hence, the probability that the three drivers would wear seat belts is 0.5**
