With the restart of gastronomy, a waiter remembers the time before the pandemic, when he received a monthly tip in addition to his salary. But it was far from being the case with every bill that a tip was given. In his experience, this only happened in about 60% of the bills that a tip was given at all. a) What is the probability that under the above assumptions of 20 invoices 1. Exactly with 10 invoices 2. if there are more than 18 invoices 3. If there are fewer than or equal to 18 invoices a tip is given. Assume that the guests tip stochastically independently of one another. And give yours when solving this subtask used distribution and its parameters with!
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.
