Find the mean of the Binomial distribution. (b) Five people each toss a coin and the odd man pays for the coffee. If the coins all show heads or all shows tails, they are tossed again. What is the probability that two decisions is reached in five tosses or fewer? (c) Find mean and variance of Normal distribution.
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.
