Assume that in a particular college, 60% of the student population is female. (i) Calculate the probability that a class of 10 students will have exactly four females. (ii) Calculate the probability that a class of 10 students will contain five, six or seven females. (iii) Calculate the probability that at least five students in class of 10 will be female.
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.
