How do I solve this? Please explain each step. My understanding is that q= .15 and p= .85 According to a 2013 study by the Pew Research Center, 15% of adults in the United States do not use the Internet (Pew Research Center website, December, ). Suppose that 10 adults in the United States are selected randomly. b. What is the probability that none of the adults use the Internet (to 4 decimals)? c. What is the probability that 3 of the adults use the Internet (to 4 decimals)? If you calculate the binomial probabilities manually, make sure to carry at least 4 decimal digits in your calculations. d. What is the probability that at least 1 of the adults uses the Internet (to 4 decimals)? I am being told the following answers that I derived are incorrect: b= .1969 c= .1298 d= .8031
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.
