Suppose that five microchips in a production run of thirty are defective. A sample of seven is to be selected to be checked for defects. a. How many different samples can be chosen? b. How many samples will contain at least one defective chip? c. What is the probability (as a percent) that a randomly chosen sample of seven contains at least one defective chip? (Round your answer to one decimal place.)
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.

a. How many different samples can be chosen?
b. How many samples will contain at least one defective chip?
c. What is the probability (as a percent) that a randomly chosen sample of seven contains at least one defective chip? (Round your answer to one decimal place.)
