For an outdoor concert by the city orchestra, concert organizers estimate that 14,000 people will attend if it is not raining. If it is raining, concert organizers estimate that 5,000 people will attend. On the day of the concert, meteorologists predict a 80% chance of rain. Determine the expected number of people who will attend this concert.
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.
