A random sample of 210 DHL packages that were shipped abroad last week have been recorded. The packages in the sample have been classified according to their size (small, medium, large) and the location these packages have been shipped from (England, Scotland, Wales). The results are shown in the table below. i. What is the probability that a randomly selected DHL package is of medium size and being shipped from England? ii. What is the probability that a randomly selected DHL package is a large sized package or being shipped from Wales? iii. Given that a randomly selected DHL package is of small size, what is the probability is being shipped from Scotland?
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.
