The following table shows the probability distribution of employees who are participating in an after-work physical exercise program in a software designing company in Sydney. No of employees Probability 4 0.1 5 0.4 6 0.3 8 0.2 What is the probability less than or equal to 6 employees are participating in the after-work physical exercise program? Compute the expected value of this probability distribution Compute the standard deviation of this probability distribution
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.
