Question

Of the last 500 customers entering a supermarket, 50 have purchased a wireless phone. If the relative frequency approach for assigning probabilities is used, the probability that the next customer will purchase a wireless phone is?

Answer 1

The probability that the next customer will purchase a wireless phone is 0.1

Explanation:

The relative frequency approach states how often something happens divided by all outcomes.

In the example some of the customers entering a supermarket purchased a wireless phone.

Here all outcomes are 500 customer entering supermarket. And among these outcome purchasing wireless phone happened 50 times.

Then the probability that the next customer will purchase a wireless phone is

`(50)/(500)`.

If we divide both sides by 50, we get
`(1)/(10)`=0.1
