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) Verify that this is a discrete probability distribution.
This is a discrete probability distribution because
between
mean
of the probabilities is
all of the probabilities are
at least one of the probabilities is
all of the probabilities are
00
and
11,
inclusive, and the
sum
sum
product
11.
(Type whole numbers. Use ascending order.)
(b) Compute and interpret the mean of the random variable X.
μx=nothing
hits(Type an integer or a decimal. Do not round.)
(c) Compute the standard deviation of the random variable X.
σx=nothing
hits(Round to three decimal places as needed.)
(d) What is the probability that in a randomly selected game, the player got 2 hits?
nothing
(Type an integer or a decimal. Do not round.)
(e) What is the probability that in a randomly selected game, the player got more than 1 hit?
nothing
(Type an integer or a decimal. Do not round.)
