At The Fencing Center, 60% of the fencers use the foil as their main weapon. We randomly survey 20 fencers at The Fencing Center. We are interested in the numbers that do not use the foil as their main weapon. A) Give the distribution of X. B) How many fencers are expected to not use the foil as their main weapon? C) Find the probability that eight do not use the foil as their main weapon. (Round your answer to four decimal places.)
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.
