A computer selects a number XX from 5 to 11 randomly and uniformly. Round all answers to 4 decimal places where possible. 1.What is the probability that the average of 38 numbers will be more than 7.5?
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.

Treat the number of months X after January 1 that someone is born as uniformly distributed from 0 to 12. Round all answers to 4 decimal places where possible.
1.What is the probability that the average birth month of the 40 people will be less than 7.6?
Suppose that the age of students at George Washington Elementary school is uniformly distributed between 5 and 10 years old. 46 randomly selected children from the school are asked their age. Round all answers to 4 decimal places where possible.
