24. for a lab activity in Science dlass the tea cher aivioles tre class of 15 into S groups of 3. as How many different graps are possible ? Combinaticns of b) unfortunatery, one of the lab benches has a Clogged drain, so there must be 4 greps instead aa OF S. So now there will be Of 4. Given this new setup how many different combina ticns of one grap of 3, and 3 groups groups are passible?

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.
