Out of 22 students in my daughter's 1st grade class, 15 got Problem 1 right and 18 got Problem 2 right. 13 students even got both Problems right. If you pick a student at random from that class, what is the probability that the student got Problem 1 OR Problem 2 right (at least one of the two)? Give the answer in percent, rounded to two digits after the decimal point.
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.
