Probability is an important branch of Mathematics. Let us talk about introduction to Probability. Probability includes the quantitative analysis of large Sets of data. 
If Outcomes number is finite, we call it as finite sample space
Some examples of Finite Sample Spaces are:
· Rolling a Dice
· Tossing a Coin
· Draw a Card
When Outcome is not discrete and Continuous then those types of sample spaces are called as Indefinite Sample space
Examples of Indefinite Sample Spaces:
· Human Height
· Length of a Chord
· Flight Arrival Time
Now understand probability sample space with the help of examples:
Example1: What will be the sample space when we will toss a Coin?
Solution: When we will toss a coin there are two probable outcomes head (H) and tail(T)
So sample space (S) = (Head, Tail)
Example 2: What will be the sample space when we will toss a Coin?
Solution: When we will toss two coins there are two probable outcomes For Coin 1: head (H1) and tail(T1)
Coin2: head (H2) and tail(T2)
Sample Space(S) = (H1, H2),(H1, T2), (T1, H2)(T1,T2)
So suppose sample set for n numbers of coins will be 2^{n}
Example3:There are 6 Numbers on a Dice which are 1, 2 , 3 , 4 , 5 , 6 .What will be the Sample space for a single throw ?
Solution: Sample space (1 , 2 ,3 ,4 , 5 ,6)
Example4: What will be the Sample Space to pull a sock from a drawer containing 15 red socks, 10 green socks, and 6 yellow socks?
Solution” S=Red, Green , yellow
Example5: What is the probability of getting an even number when rolling a die?
P = P(2) + P(4) + P(6)
Example 6: What will be the Sample Space to pick a ball from a drawer containing 15 yellow balls, 10 white balls, and 16 red balls?
Solution” S= Yellow, white, red
