Solving Math Expected Value

Introduction to solving math expected value:

Math is to used all over the world as an important tool in a lot of fields, including natural science, engineering. We will learn the math concepts and find the expected value in math with help of example problems. This article provides some of the math concepts and solving expected value help with example problems.

Geometry in Solving Math Expected Value:

Let us we will solving geometry problem in math and finding expected value.

Example 1:

Locate the area of a parallelogram base is 22 and a height is 16 centimeters.

Solution:

Formula for area of parallelogram:

A=b`xx` h.

=22 `xx` 16

=352cm2

A=352cm2

Set theory in math:

Let us we will solving set theory problem in math and finding expected value.

Example 2:

Find A∩B and A∪B, when A = {3, 13, 33, 35, 36} and B = {33, 34, 35, 36}.

Solution:

Given, A = {3, 13, 33, 35, 36} and B = {33, 34, 35, 36}.

A∪B = {3, 13, 33, 35, 36} ∪ {33, 34, 35, 36}

= {3, 13, 33, 34, 35, 36,}

A∩B = {3, 13, 33, 35, 36} ∩ {33, 34, 35, 36}

= {33, 35, 36}

Probability in Math:

Let us we will solving probability problem in math and finding expected value.

Example 3:

From the following values,

2.1, 2.2, 2.7, 2.8, 3.3.

Locate the probability for,

1. above 2.5 values

2. below 2.5 values

Probability for finding above 2.5 scores:

Above 2.5 scores = 2.7, 2.8, 3.3.

In the given scores the above 2.5 scores probability values are (2.7, 2.8, 3.3).

Probability for above 2.5 scores = 3

Total scores = 5

Probability =`("Above 2.5 values")/("Total given values")` .

Total scores = 5.

Probability for above 2.5 scores = `(3)/(5)` .

Answer: `(3)/(5)`

Find the probability for below 2.5 scores:

Solution:

The given scores are,

2.1, 2.2, 2.7, 2.8, 3.3.

Below 2.5 scores are 2.1, 2.2.

Formulas for getting probabilities for below 2.5 scores are

Probability =`("Below 2.5 values")/("Total given values")`

Here below 2.5 values = 2

Total given values= 5.

So the probability for below 2.5 values= `(2)/(5)` .

Answer:

= `(2)/(5)`.

Statistics in math:

Let us we will solving statistics problem in math and finding expected value.

Example 4:

Find the median in the following numbers.

60.5, 201.22, 15.9, 36.7, 52.8

Solution:

The given numbers are 60.5, 201.22, 15.9, 36.7, 52.8

The ascending order is,

15.9, 36.7, 52.8, 60.5, 201.22

So the median value of the given number is 52.8.

=52.8.

That’s all about solving math expected value.
