7) If 20% of the people who shop at a local grocery store buy apples, what is the probability that it will take no more than 5 customers to find one who buys apples? Which simulation design has an appropriate device and a correct trial for this problem?

Kindly check the Explanation section.

Step-by-step explanation:

Step one: given the following data or parameters or infomation in the question as: "20% of the people who shop at a local grocery store buy apples" and we are asked to determine the probability that it will take no more than 5 customers to find one who buys apples. Therefore, the simulation design that has an appropriate device and a correct trial for this problem is given below in step two and step three.

Step two: use a random digits table

and select one digit numbers where 0- 1 is a customer who buys Apple and 2 - 9 is a customer that do not buy Apple.

Step 3: keep selecting one digit numbers until the numbers fall within 0 - 1. Then, record the numbers selected.
