Insulin pens used to administer a patient's insulin at hospitals have a malfunction rate of 9%. This meant that out of a box of 200 pens, 18 are defective in some way and must be discarded. a) Find the probability of randomly selecting 3 defective insulin pens in a row from a brand-new box of 200 pens if a defective pen is immediately discarded. b) Find the probability of randomly selecting 3 effective insulin pens in a row from a brand-new box of 200 pens, if an effective pen is immediately used and discarded.
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.
