What is the probability of obtaining exactly four tails in five flips of a coin, given that at least three are tails? (Enter the probability as a fraction.)   "Somebody gave me the equation using the binomial distribution to find the probability b(x; n,p) = nCx*pxq(n-x), but I don't get the equation yet, please give me another equation of probability ( P(A I B) = P (A AND B) / P(B) ), or easier one then I will recognize them. The Anser is 5/16 = Correct

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.
