Q4. a) How many different arrangements of the word PARRAMATTA are possible? b) A committee of four people is to be chosen from a group of nine candidates, consisting of five women and four men. 1) How many different committees are possible if there are no restrictions on the choice? 2) b) If the committee is chosen at random, what is the probability that it contains at least as many women as men? c) If the letters of the word SPECIAL are written in a random order, what is the probability that no two vowels are next to each other?
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.
