You decide it would be fun to go to a magic show. The magician picks you out of the crowd and writes down 2 digits (0-9) at random without replacement. He writes them in the order picked. What is the probability that he has written the first 2 digits of your address? Assume there are no repeats of digits in your address. Give your answer as a fraction.
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.
According to the given information it is required to find the probability the magician has the first 2 digits of my address.
Note that my address has fixed digits from 0 to 9, and the digits in my address is non repeating too, so first two digits of my address can be considered any two different digits(0-9) say m and n where m and n are not different.
