Based on a Harris Interactive poll, 20% of adults believe in reincarnation. Assume that six adults are randomly selected, and find the indicated probability. P(k successes in n trials)?!/?!(?−?)! ∙ ??(?−?)?−? or ?!/?!(?−?)!∙??∙??−? a)What is the probability that exactly threeof the selected adults believe in reincarnation? b) What is the probability that fewer than five of the selected adults believe in reincarnation
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.
