The table below shows the number of science and non-science majors among a group of 140 international and domestic students. Science Non-science Total Domestic 55 25 80 International 45 15 60 Total 100 40 140 Using the data from this table, compute the following probabilities. Enter your answers as a decimal number rounded to three decimal places. If one person in this group is chosen at random, what is the probability that this random student is domestic or a science major: If the chosen person is a science major, what is the probability that this student is domestic:
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.
The table below shows the number of science and non-science majors among a group of 140 international and domestic students.
Science | Non-science | Total | |
