Probability Calculator

Halo. I'm back again to post my blog. For this time, I will tell you about a Probability calculator. If you like math theory, you must check this out. Probability calculator is the method of finding the possible ways of some arrangements. In detail the below section would help to understand more with examples on probability calculator.

The Probability Calculator computes the probability of one event, based on probabilities of other related events. Probability calculator handles problems that can be addressed using three basic rules of probability the subtraction rule, addition rule, and multiplication rule. For problems that require Bayes' rule, use the Bayes' Rule Calculator. It only contains the fields in which we need to enter the values through which we can calculate the desired probability. Based upon the questions the fields change.

Example: Find the probability by Probability Calculator to get a tail when we toss a coin?

Number of sides on coin = 2 (sample space)

It only has one tail on a coin

The probability of showing tail = 1/ 2.

Equivalent Fractions

Equivalent fractions are the types of fractions in which the values of the numerator and denominator value remains the same.

Below examples on equivalent fractions would be beneficial for you to get practiced with this concept.

Learning equivalent fractions with examples:

Consider the fractions 1/6 and 5/30.

Observing these two fractions, the numerator of the first fraction is 1 and the denominator of the first fraction is 6 whereas the numerator of the second fraction is 5 and denominator is 30. Both the fraction seems to be different.

Let us simplify the second fraction 5/30, that is divide the numerator and denominator with a common factor of 5 and 30. The common factor of 5 and 30 is 5.

So let us divide 5 and 30 with 5.So, 5/30 = 1/6.

Now compare the two fractions. They are same.

So, 1/6 and 5/30 are called as equivalent fractions.

Equivalent fraction seems to be different but they possess same value.

Prime Factorization
Prime Factorization
is the process of find which prime numbers you need to multiply together to get the original number. The process of find this number is called integer factorization, or prime factorization. Prime number does not have any factors apart form itself and 1, but 1 is not a prime number.
What is Prime Factorization?

Prime number is nothing but which has no factors other than itself and 1, but 1 is not regarded as a prime number. A factor which is prime number is called a prime factor.

finding prime factorization of a number, divide all its factors until every remaining integer should be prime. Final result of prime numbers is the prime factorization of the original integer. For example: 36

36 = 2 × 18 = 2 × 2 × 9 = 2 × 2 × 3 × 3

The prime numbers 30 are thus 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. A factor which is a prime number is called prime factor. All number can be expressed as a product of prime numbers.

Hope you enjoy this post. So, any questions ?
