A fair coin is flipped 3 times. What is the probability that (a) the first flip was heads given that there was a total of 1 head among all three flips (b) there are exactly 2 heads seen given that the first flip was heads (c) the first flip was a head given that there was at least 1 head among the 3 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.
