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.
In a survey of 99 families in Karachi, 45 were low income families who at some point in
time were involved in electricity theft. 13 were low income families who never did any
violation. 16 were high income families who involved in electricity theft, and 25 high
income families never did any violation.
If One of these subject is randomly selected, what is the probability of:
i. Low income families or someone who did electricity theft.
ii. Low income families or someone who did not do violation.
iii. High income families or someone who did electricity theft.
