At a particular college there are a total of 75 teachers. The table below shows the number of teachers in each age group. What is the probability that. Age group Number in that age group 30 – 39 10 40 – 49 20 50 – 59 30 60 – 69 15 what is the probability that none of the four people selected are in their 50s? Give answer to 3 decimal places.
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.
