If 30% of the people who shop at a local grocery store buy chocolate ice-cream, what is the probability that it will take at least 5 customers to find one who buys chocolate ice-cream?

Which simulation design has an appropriate device and a correct trial for this problem?

A) Roll a fair die where 1,2, and 3 are buying chocolate ice-cream and the other numbers are not buying chocolate-ice cream. Roll the die until you get a 1,2,3. Record the number of rolls it took you.

B) Using a random digits table select one digit numbers where 0-2 is a customer who buys chocolate ice cream and 3-9 is a customer who does not. Keep selecting one digit numbers until you get a 0-2. Record the number of digits selected.

C) Using a random digits table select one digit numbers where 0-3 is a customer who buys chocolate ice cream and 4-9 is a customer who does not. Keep selecting one digit numbers until you get a 0-2. Record the number of digits selected.

D) Spin a spinner that is split up into 5 sections, where 1 section is a success of buying chocolate ice-cream and the other four sections are not buying chocolate ice-cream. Keep spinning until you get someone that buys chocolate ice-cream. Record the number of spins it took you

Using a random digits table select one digit numbers where 0-2 is a customer who buys chocolate ice cream and 3-9 is a customer who does not. Keep selecting one digit numbers until you get a 0-2. Record the number of digits selected. This is the correct simulation design and a correct trial.

What is Percentage?

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used.

What is simulation design?

Design simulation helps manufacturers verify and validate the intended function of a product under development, as well as the manufacturability of the product. The word “simulation” is often used as generic term for computer-aided engineering (CAE).

What is probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

According to question,30% of the people who shop at a local grocery store buy chocolate ice-cream.

30% of the people who shop at a local grocery store buy chocolate ice-cream means probability is [tex]\frac{3}{10}[/tex].

Let consider number from [tex]0[/tex] to [tex]9[/tex].

If we consider [tex]0-2[/tex] numbers as the person who buys chocolate ice cream which is three numbers out of ten and fits the [tex]30[/tex]% and the probability of [tex]\frac{3}{10}[/tex] since [tex]3-9[/tex] numbers is a customer who is not buying the chocolate ice cream.

Hence we can conclude that Option B is correct answer.
