Help with dice probability

Introduction to solving dice probability:
Let us see ,solving the dice probability. Probability means "nothing but calculating the chance for a particular event to occur". Dice based problems are the best examples for explaining about the probability.

Let E be an experiment involving rolling two dices and recording the value on top of each die. The notation for this sample space
is: S = {(i, j),i =1,2,3,4,5,6, j =1,2,3,4,5,6}
Note this is a discrete and finite sample space. Let us see the probability concepts, solving problem using the dice problems.

Solving Dice Probability:

Let us see some of the examples of solving dice probability.

Example 1:
What is the probability of a die showing a 2 or a 5?
Solution:
P (2) = 1/6
P (5) = 1/6
P (2 or 5) = P(2) + P(5)
= (1/6) + (1/6). This could also help us on square yard

Triangles Formulas

Introduction to Triangle:
In this article let me help you on triangles formulas. Triangle is a type of polygon having three sides only. We have six types of triangle based on sides of a triangle or angles of a triangle.

Based on side, we have equilateral triangle, isosceles triangle and scalene triangle.
Based on angle, we have acute triangle, right triangle and obtuse triangle.
In this article, we shall see about triangle formulas.

Triangle Formula:

In this article, we are going to learn area of a triangle. Area of Triangle is also represented by a letter A.
The formula for Area of a triangles is half of the product of base and height of a triangle.

That is Area of a Triangle = 1/2 x Base x Height This could also help us on factoring contract
A = 1/2 x Base x Height

Area of a Triangle can be measured by square units.
Let us see sample problems for calculating area of a triangle using formula.

Adjacent Angle

In this section let me help you on adjacent angle. Keep reading if you have any doubts do leave your comments. When two straight line meet at a common point, they form an angle.

$\overline {AB}$ and $\overline {AC}$ are called arms of the angle BAC. The point 'A' is called the vertex. The angles formed by the two rays AB and AC is denoted by the symbol LBAC. If there is only one angle at A, then the angles BAC may be denoted by LA.
In a given plane two lines intersect at only one point. The angles are measured with the help of a protractor. The measure of an angle is called its magnitude. This could also help us on not equal sign

The major types of angles are as follows

• Acute Angle
• Right angle
• Obtuse angle
• Straight angle
• Reflex angle
• Angle relations

How to do fractions?

Introduction to how do you do fractions:

In this section let me help you understand on how to do fraction. Fraction is a certain part in a whole thing. Fraction is represented by a numerator and denominator. The upper part of the fraction is called as numerator and the lower part in the fraction is called denominator. Fraction can be added, subtracted, Multiplied and divided. These are the basic operation we do with fraction.

Classification of Fractions:

Fraction are classified as

* Proper fraction
* Improper fraction
* Mixed fraction. This could also help us on thermometer worksheet

Help on Air Density Calculator

In this article let me help you on air density calculator. The application of knowledge of density of air at STP and various temperature is important for various disciplines in science.density of air can be defined as the mass of the dry or humid air per unit volume.

Introduction to density of air at stp
Density of the air depends on various factors like the temperature, altitude, pressure as well as the presence of humidity. here i am giving the method of calculating the density of the dry air at STP.
The STP conditions are 273K and 1 atmospheric pressure or 101325.03 pascal , to calculate the density in Kg/m^3, the universal or molar gas constant (R) has to be converted in to specific gas constant.
The molar mass of the dry air =28.97 g. This could also help us on logarithm table
The specific gas constant = R / 28.97J g-1K-1
= 8.314 / 28.97J g-1K-1
= .28698 Jg-1K-1
= 286.98 JKg-1 K-1 (JOULES PER Kg PER KELVIN)

Help on Numerator

Introduction to Numerator:

In this lesson let me basically put down on numerator which will help you on understand better.

* In general, the term numerator is defined as follows,
* A numerator is a number written over the line in a common fraction which is identified the total number of parts in the whole part like as2 in ½.
* Mathematically, a fraction contains dividend and divisor. Thus the dividend of fraction is called numerator.
* A numerator is a number in a fraction. Also it is called as nominator.
* The place of top number of a fraction is named as numerator.

Numerator Example:

Adding proper fractions for numerator:

Step1: verify whether the denominators are the similar or not (If not means, get LCD by cross-multiplying)

Step2: Add the numerators and locate the result on the same denominator

Step3: Finally decrease the fraction (if needed)

Example: This could also help us on perpendicular bisector

Find the numerator: 1 / 7 + 1 / 7

Step1: Fraction of both denominators is the same.

Step2: Add the numerators

1 / 7 + 1 / 7 = (1+1) / = 2 / 7

Step3: No need of reduction

2 / 7 = 2 / 7

So the final numerator is 2.

Note on Uniform Motion

Introduction to Uniform Motion

In this lesson let me help you on uniform motion. A motion is said to be uniform if the particle covers equal distances in equal intervals of time, however small these intervals of time may be , always in the same direction. Strictly speaking , no motion is uniform.

When a particle has uniform motion, neither the magnitude nor the direction of velocity changes , so the velocity is constant in uniform motion and is equal to Instantaneous velocity of the particle.

So uniform is a relative concept. If an object A is in uniform motion relative to another object B, then from B's view there appear to be no force applied to A; i.e. it appears to be neither accelerating nor decelerating, nor changing directions or moving in a curve. The same should apply vice versa.This could also help us on examples of physical changes

when a particle possess uniform motion, it's velocity- time graph is a straight line parallel to time axis.If the velocity of the particle is taken as positive, the straight line is taken above the time axis and if it is negative, then the V-t graph will be a straight line below the time axis
