19). A university student leaves her iClicker device behind with probability of 1/4 each time she attends a class. She sets out with her iClicker device to attend 5 different classes (each class is in a different lecture theatre). a) If she arrives home without her iClicker device and she is sure she has the iClicker device after leaving the first class, what is the probability (to at least 3 significant figures) that she left it in the 5th class? Probability = ? b) If she arrives home without her iClicker device (after attending 5 classes), what is the probability (to at least 3 significant figures) that she left it in the 5th class? 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.
