60% of the employees in a specialized department of a large software firm are computer science graduates. A project team is made up of 9 employees. Part d) There are 54 such projects running at the same time and each project team consists of 9 employees as described. On how many of the 54 project teams do you expect there to be exactly 3 computer science graduates? Give your answer to 1 decimal place. Part e) I meet 20 employees at random. What is the probability that the third employee I meet is the first one who is a computer science graduate? Give your answer to 3 decimal places. Part f) I meet 27 employees at random on a daily basis. What is the mean number of computer science graduates among the 27 that I meet? Give your answer to one decimal place.
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.
