A particular item is stocked in four different sizes. An order is received for 2 items, but the sizes are not specified. The clerk fills the order by guessing and simply slects 2 items and ships them out. What is the probability that the 2 items shipped were the ones desired? Neither item shipped was the one desired.
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.
