60% of all computers sold by a computer retailer are laptops desktop models. The type of computer purchased by each of the next 5 customers will be noted. Define a random variable x as x= numbers of computers among these 5 that are laptops ( hint: what type of distribution is this?) a. Find the probability that no laptops are sold among the next five
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.
60% of all computers sold by a computer retailer are laptops desktop models. The type of computer purchased by each of the next 5 customers will be noted. Define a random variable x as
x= numbers of computers among these 5 that are laptops
( hint: what type of distribution is this?)
a. Find the probability that no laptops are sold among the next five computers. Round final value to three decimal places.
B. Find the probability that at least one but no more than four laptops are sold among the next five computers. Round final value to three decimal places
