An experiment consists of flipping a weighted coin with Pr[H]=0.2. The experiment ends when either heads is flipped 3 times or tails is flipped. What is the probability that heads was flipped at least once given the coin was flipped at most two times?
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.
