A tank initially holds 410 liters of brine solution containing 7 kg of salt. At t=0, another brine solution containing 0.4 kg of salt per liter is poured into the tank at the rate of 18 liters/min. while the well-stirred mixture leaves the tank at the same rate. Find the (a) the amount of salt in the tank at any time t and (b) the time at which the mixture in the tank contains 15 kg of salt.

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.
