A number is randomly selected from the set {1,2, --. , 23!} (note that there is a factorial!). For k = 1,2,-, 20, define the events Ak = {the selected number is divisible by k}. Find the following probabilities. (a) P(A10),P(A15). (b) P(A10 A15 (c) P(A10 U A15).
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.

Probability:
The probability of an event is the proportion of the number of times the event occurs to the total number of events that is the sample space. It gives the chance of a particular event to be the output for an experiment. (OR) It is the ratio of the number of events that occur to the sample space of the experiment. It is basically the chance of getting some particular events from the experiment.
Conditional Probability:
It the probability with certain conditions that are applied to the events and calculating its chance.
