A coin is biased so that heads is twice as likely as tails.For three independent tosses of the coin, find(a) the probability distribution of X, the total numberof heads;(b) the probability of getting at most two heads.
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.
A coin is biased so that heads is twice as likely as tails.

of heads;
