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
= 2/6
= 1/3
The Probability of a die showing 2 or 5 is 1/3..
