A person with $2 in her pocket bets $1, even money,on the flip of a coin, and she continues to bet $1 as longas she has any money. Draw a tree diagram to show thevarious things that can happen during the first four flipsof the coin. After the fourth flip of the coin, in how manyof the cases will she be(a) exactly even;(b) exactly $2 ahead?
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.

on the flip of a coin, and she continues to bet $1 as long
as she has any money. Draw a tree diagram to show the
various things that can happen during the first four flips
of the coin. After the fourth flip of the coin, in how many
of the cases will she be
(a) exactly even;
(b) exactly $2 ahead?
