A shopkeeper sells a saree at 8% profit and the sweater at 10% discount, thereby, getting a sum of Rs. 1008. If she had sold the saree at 10% profit and the sweater at 8% discount, she would have got 1028 Rs. Than find the cost of saree and list price (price before discount) of the sweater.
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.
A shopkeeper sells a saree at 8% profit and the sweater at 10% discount, thereby, getting a sum of Rs. 1008. If she had sold the saree at 10% profit and the sweater at 8% discount, she would have got 1028 Rs. Than find the cost of saree and list price (price before discount) of the sweater.
