A warehouse employs 25 workers on first shift, 17 workers on second shift, and 10 workers on third shift. Eight workers are chosen at random to be interviewed work environment . Find the probability of choosing exactly five first -shift workers
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.

According to the combination rule, if r distinct items are to be chosen from n items without replacement, in such a way that the order of selection does not matter, then the selection can be made in (nCr) = n! / [r! (n – r)!] = [n (n – 1) … (n – r + 1)] / r! ways.
