5 balls are drawn with replacement from a bag containing 4 red balls and 6 black balls. (Round your answers to five decimal places.) (a) Find the probability that 2 of the balls will be red. (b) Find the probability that all 5 balls will be black. (c) Find the probability that at least 3 of the balls will be black.
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.
