Suppose that you flip a fair coin 6 times in a row and record each results. We want to find the probability that you get both heads and tails. (a) How many different outcomes can you get? (b) How many different outcomes contain both heads and tails? (c) What is the probability that you got both heads and tails?
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 that you flip a fair coin 6 times in a row and record each results. We want to find the
(a) How many different outcomes can you get?
(b) How many different outcomes contain both heads and tails?
(c) What is the probability that you got both heads and tails?
Here, the coin is tossed 6 times.
Number of outcomes=2^6=64.
a)
The different number of outcomes is 64.
