Suppose your experiment consists of repeatedly throwing two fair coins, with "success" when both coins come up "heads". What is the probability of having exactly 2 successes out of 3 trials?
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.
Suppose your experiment consists of repeatedly throwing two fair coins, with "success" when both coins come up "heads".
What is the probability of having exactly 2 successes out of 3 trials?
Enter your number as "0.???", rounding to three digits after decimal point. For example, if your answer is 1/3 you would enter 0.333, and if your answer is 2/3 enter 0.667.
Suppose your experiment consists of repeatedly throwing two fair coins, with "success" when both coins come up "heads".
