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.
you roll a six-sided die.what is the probability that it is an even number or less than five
When a six-sided die is rolled the sample space is
S={1,2,3,4,5,6}
n(S)=6
P(even number or less than five)=?
Let A be event that it is even number
The possible outcomes for the event “even number” are {2, 4, 6}.
n(A)=3
B be event that it is less than 5
The possible outcomes for the event “number less than 5” are {1, 2,3,4}.
n(B)=4
n(A and B)=2
P(A or B)=?
