Question

the mayor of a town wants to find the probability that families with three children have all girls. which simulation will best model the situation?
a numbered cube rolled 3 times
three coins flipped 10 times
a spinning wheel with three colors, spun twice
a random - number generator, generating numbers from 1 to 10, pressed twice

Explanation:

The probability of having a boy or a girl is similar to the probability of getting heads or tails when flipping a coin (a binary - outcome situation). Having three children is like performing three independent binary - outcome events. Flipping three coins multiple times (in this case 10 times) simulates the situation of having three children multiple times. A numbered cube has 6 outcomes, a spinning wheel with three colors has 3 outcomes, and a random - number generator generating numbers from 1 to 10 has 10 outcomes, which do not represent the binary (boy/girl) situation well.

Answer:

B. three coins flipped 10 times
