Boys and girls: A couple plans to have children until a girl is born, but they will have no more than three children. Assume that each child is equally likely to be a boy or a girl. Let Y be the number of boys they have. a.Find the probability distribution of Y. b. Find the mean μY . c. Find the standard deviation σY .
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.
