n a given company, employee should sign in using the biometric time clock. There are 3 devices in the company and the probability that it works is 95%. Let x be the random variable of the number of devices working at a given day. 1. Construct the probability distribution of x. 2. Find the mean value and interpret it. 3. Find the standard deviation and interpret it.
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.
