One number from the set {1, 2, 3} is selected at random. Then a fair coin is flipped x times, where x equals the number that was chosen randomly from the set. What is the probability that 3 was chosen from the set given that (a) no heads were seen on any of the coin flips (b) exactly 1 head was seen on the coin flips (c) exactly 2 heads were seen on the coin flips (d) exactly 3 heads were seen on the coin flips?
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.
