A student takes a 25 question multiple choice eam. Each question has 3 choices for each question. The student is unprepared and guesses on each question. Find the probability of getting 15 or more out of 25 problems correct? Also: If there is a manner to use the TI-83 to solve, please advise. Best Regards, Sabrina Topp
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.
