QI Tom participates in a competition where he has 10 tries to hit the target His probability of success is 70% Use Tables| a) What is the probability he will hit the target exactly 8 times b) No more then 7 times c) At least 8 time
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.
Here it is given that-
total number of tries (n) = 10
probability of success (p) = 70%==0.7
As n and p are given so the given problem follows the Binomial distribution.
