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.
calculus
We have to decide whether the given series are convergent:
a)
Using Ratio Test, we get,
Now, as the value of the limit is greater than 1, the test tells us that the series diverges.
b)
Consider another series, , and let . Clearly, is convergent.
Then, we can see that , as,
Therefore, we have a convergent series, , such that , and so, by comparison test, we can say that the series is convergent.
