A math teacher is not happy about the attendance of her class at her online lectures. She decides that she will not lecture unless at least twelve of fifteen students enrolled in the class are attending the lecture. Each student will connect to the online lecture with a probability of 0.2437 if there is a good internet connection and a probability of 0.7311 if there is a bad internet connection. The probability that there is a bad internet connection is 0.1. Given that there is a bad internet connection on a given day, write down the expression for the probability that the teacher will teach her class and calculate the probability.
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.
