Suppose each blood donor arriving at a clinic has Type O blood with probability p = 0.5, independently of all other donors, and that 10 Type O donors are needed. a) What is the probability that exactly 3 non-Type O donors will arrive prior to the requisite 10 Type O donors, rounded to two decimal places? b) What is the expected value of the number of non-Type O donors that will need to be screened before the requisite 10 Type O donors have arrived?
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.
