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.
Blood Only 4% of people have Type AB blood.
a) On average, how many donors must be checked to find
someone with Type AB blood?
b) What’s the probability that there is a Type AB donor
among the first 5 people checked?
c) What’s the probability that the first Type AB donor
will be found among the first 6 people?
d) What’s the probability that we won’t find a Type AB
donor before the 10th person?
