n a district, 65% of the total population is in favor of rising the traffic challan. During a survey of that region, you sample 100 people. Then find the probability that those people who participated in survey will contain (a) between 60 and 70 inclusive who are in favor; (b) at least 50 who are in favor of the proposition; (c) Less than 75 in favor.
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.
