At one liberal arts college, students are classified as humanities majors, science majors, or undecided. The chances are 40% that a humanities major will change to a science major from one year to the next, and 35% that a humanities major will change to undecided. A science major will change to humanities with probability 0.35, and to undecided with probability 0.25. An undecided will switch to humanitios or science with probabilities of 0.40 and 0.20, respectively. Complete parts (a) and (b) below. (a) Find the long-range prediction for the fraction of students in each of these three majors. First, find the transition matrix P. Let the first state be that a student is a humanities major, the second that a student is a science major, and the third state that a student is undecided. (Type an integer or decimal for each matrix element.) Find the long-range prediction for the fraction of students in each of these three majors. The long-range prediction is humanities, science, and undecided. (Type integers or simplified fractions.) (b) For a regular 2-by-2 matrix having column sums of 1, the equilibrium vector is Make a conjecture, and describe how this conjecture, if true, would allow you to predict the answer to part (a) with very little 2 2 computation. A regular 3-by-3 matrix having column sums of 1 has an equilibrium vector of (Type an integer or simplified fraction for each matrix element.) How can this conjecture be used to predict the answer to part (a)? The column sums of the transition matrix in part (a) V equal to 1. The conjecture V be used to find the long-range predictions for the fraction of students each major.

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.
