In a certain country, the true probability of a baby being a boy is 0.513. Among the next eight randomly selected births in the country, what is the probability that at least one of them is a girl? The probability is (Round to three decimal places as needed.)
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.
Solution:
Let X be the number of girls and n be the sample number of births.
From the given information, probability of a baby being a boy is 0.513 and n=8. The probability of a baby being a boy is 1–0.513=0.487.
