Among 1,000 freshmen pursuing a business degree at a university, 520 are enrolled in an economics course, 490 are enrolled in a mathematics course, and 290 are enrolled in both an economics and a mathematics course. What is the probability that a freshman selected at random from this group is enrolled in exactly one of these two courses? 300/1000 820/1000 690/1000 430/1000 560/1000 None of these
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.
