In a recent survey of 619 Salinas residents, 437 stated they experienced significant traffic delays within the last month. 1. If one of the 619 residents is selected at random, what is the probability they have experienced delays? 2. If one of the 619 residents is selected at random, what is the probability they did not experience delays?
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.
Given:
Total number of Salinas residents = 619
The number of residents who experienced delays = 437
It means,
The number of residents who did not experience delays= 619437 = 182
