Examples of the use of Newton’s binomial

Newton’s binomial provides a method to calculate these coefficients quickly and efficiently. There are several examples of the use of Newton’s binomial in various fields of science. mathematics, physics and engineeringas in the theory of probability, calculus and combinatorics.

For example, in probability theory, the binomial distribution is used to model a sequence of binary experiments independent trials, and the coefficient of a particular term in the expansion of (a + b)^n gives the number of ways that a particular event can occur n times out of a total of n independent trials.

Similarly, in calculus, Newton’s binomial is used to solve problems related to polynomials and functionswhile in combinatorics it is used to count the number of possible combinations of objects that can be formed from a given set.

Here are some detailed examples of how Newton’s binomial can be used:

Example 1: Expand the binomial (2x + 3)^3

To expand this binomial using Newton’s binomial, one must first remember the formula:

(a + b)^n = C(n,0)a^nb^0 + C(n,1)a^(n-1)b^1 + C(n,2)a^(n-2) b^2 + … + C(n,n)a^0 b^n

Where C(n,k) represents the binomial coefficient, which can be calculated as:

C(n,k) = n! / (k!(nk)!)

Applying Newton’s binomial formula to the binomial (2x + 3)^3, we have:

(2x + 3)^3 = C(3,0)(2x)^3 3^0 + C(3,1)(2x)^2 3^1 + C(3,2)(2x)^1 3 ^2 + C(3,3)(2x)^0 3^3

Simplifying each term, we get:

(2x + 3)^3 = 8x^3 + 36x^2 + 54x + 27

Therefore, the expansion of the binomial (2x + 3)^3 is 8x^3 + 36x^2 + 54x + 27.

Example 2: Calculate the probability of getting two heads when tossing a coin three times..

To calculate this probability using Newton’s binomial, we must first remember that the binomial distribution can be expressed as:

P(X=k) = C(n,k) p^k (1-p)^(nk)

Where P(X=k) is the probability of obtaining k successes in n trials, p is the probability of success in a single trial, and (1-p) is the probability of failure in a single trial.

In this case, n=3, k=2 (we want to get two heads), p=1/2 (the probability of getting heads in a single toss) and (1-p)=1/2 (the probability of getting tails). in a single launch). Therefore, the probability of getting two heads when tossing a coin three times is:

P(X=2) = C(3,2) (1/2)^2 (1/2)^1 = 3/8

Therefore, the probability of getting two heads when tossing one coin three times is 3/8.

These are just a few examples of how Newton’s binomial can be used in practical situations. In general, this formula is widely used in mathematics, physics, chemistry, finance, and other areas for calculating probabilities, modeling systems, and make predictions.

Understand and apply the binomial theorem requires practice, and luckily there are several resources available for people to improve their skills.
