On most social media platforms, 64% of all ads are targeted ads. Ad-blockers attempt to block such targeted ads before they are delivered to the user. One such ad-blocker has a 42% chance of blocking an ad if it is actually targeted, and a 19% chance of blocking an ad that is not targeted. a. If an ad is blocked by the ad-blocker, what is the probability that it was not a targeted ad? b. If the user is served an ad which was not blocked, what is the probability that it was targeted?
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.
