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.
Assume that 35% of those taking driving tests pass the test fhe first time
(a) Out of 20 people taking the test for the first time, what is the probability that at deast 10 will pass?
(b) How many out of the 20 people are expected to pass?
(c) How many people taking the test for the first time need to be selected, to be 95.5% sure that at least 3 of them will pass the test?
