In the results of the gender-selection technique, 875 births consisted of 444 baby girls and 431 baby boys. In analyzing these results, assume that boys and girls are equally likely. The probability of getting exactly 444 girls in 875 births is ?
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
