According to a study, the probability that a randomly selected teenager studied at least once during the week was only 0.52. Let X be the number of teenagers who studied at least once during the week. a. What is the probability that exactly 5 of the students in your study group of 10 have studied in the last week? b. What is the probability that at least 5 of the students in your study group of 10 have studied in the last week? c. What is the probability that at most 4 of the students in your study group of 10 have studied in the last week?
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.
