Question

a town has 10,000 two - child families. design a simulation to estimate the percentage of two - child families with two girls. choose a simulation tool, explain one trial, and describe the headings for a table in which you would record the outcomes.

Explanation:

Step1: Choose a simulation tool

We can use a coin - toss simulation. A fair coin has two outcomes (heads and tails), similar to the two possible genders (boy and girl). Let heads represent a girl and tails represent a boy.

Step2: Describe one trial

In one trial, we toss the coin twice. Each toss represents the gender of one child in the two - child family. For example, if we get heads on the first toss and heads on the second toss, it represents a family with two girls.

Step3: Describe table headings

The table could have the following headings: "Trial Number", "First Toss Outcome", "Second Toss Outcome", "Family Has Two Girls (Yes/No)".

Answer:

Simulation tool: Coin - toss. One trial: Toss a coin twice. Table headings: "Trial Number", "First Toss Outcome", "Second Toss Outcome", "Family Has Two Girls (Yes/No)"
