74% of all students at a college still need to take another math class. If 37 students are randomly selected, find the probability that a. Exactly 25 of them need to take another math class. b. At most 26 of them need to take another math class. c. At least 27 of them need to take another math class. d. Between 23 and 29 (including 23 and 29) of them need to take another math class.
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.
