The following table represents the numbers of students in a section of Math 120 with declared or undeclared majors along with their class. What is the probability that a student is a sophomore, given that they have a declared major? Enter your answer in decimal form and round to four decimal places if rounding is necessary. Probability that a student is a sophomore, given that they have a declared major = Blank 1. Calculate the answer by read surrounding text. Freshman (F) Sophomore (H) Junior (J) Total Declared (D) 114 36 4 154 Undeclared (U) 9 7 1 17 Total 123 43 5 171
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.
