A chemical compound contains 3 particles of a reactant and 6 particles of a catalyst. Particles are removed from the compound at random, and after the removed particle is examined, it is returned back to the chemical compound together with an additional particle of the same type. We call this process of removal/return a "reaction". (a) Assume there are two consecutive reactions. Compute the probability that the first and the second removed particle is a reactant. (b) Compute the probability that at least one of the two removed particles is a reactant. (c) Assume now a third consecutive reaction occurs. Compute the probability that the third removed particle is a catalyst, given that exactly one of the first two is a reactant.

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.
