**Question:**Statistics show that about 42% of Americans voted in the previous national election.If three Americans are randomly selected, what is the probability that **all** of them voted in the previous national election?**Options:**- 0.20- 0.17- 0.06- 0.42- 0.07**Explanation:**This problem is asking for the probability that all three selected Americans voted, given that the voting rate is 42%. Assuming independence, the individual probability for each person voting is 0.42. Therefore, the probability that all three voted is $0.42 \times 0.42 \times 0.42$.**Solution:**Calculate $0.42^3$.The correct answer is 0.06.

Concept explainers

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
