I was searching for the meaning of Paradox and i found the defintion for it which is "A paradox is a statement that at first seems to be absurd or self-contradictory but which may on fact turn out to be true."
Im having a little trouble understanding that...
Could anyone please give me an example of a paradox?

Yes, check out the birthday paradox on wikepedia. In essence,
this paradox demonstrates that mathematical truth contradicts naive intuition.
The problem: If 23 people are randomly selected it is about a 50- 50 probability that at least 2 will have the same birthday. Most people when confronted with this problem will intuitively estimate that selecting only 23 people will be considerably less than a 50-50 chance of having at least 2 people with the same birthday.
They will also estimate that to get to a 50/50 probability it will have to be considerably more than 23.
At wikepedia they give several different mathematical approaches to solve this problem. The best and simplest is;
A simple exponentiation
P(n)= 1-(364/365) ^(nC2)=
1-(364/365)^(23C2)=
1- (.99726) ^ (253)=
1- (.499488)=
.500511872
(nC2) is also expressed as n Choose 2...This is a factorial.
Therefore (23Choose 2) gives you 253 possible combinations.
(23x22/2x1)=253 This will be the exponent for (364/365).
With 60 people randomly chosen, this exceeds 99% chance of getting at least 2 with the same birthday.
P(n) =1- (364/365)^(60C2)=
1-(.997260274)^(1770)=
1-.00778178=.99221822
In essence, some Paradoxes can be proven false, as this one has been demonstrated. Some of our false truths throughout history have been based on naive intuition and only resolved with counter intuitive approaches. I hope this helps! GL

Here's one I found on wikipedia

How about: Walking a thousand miles but only moving two feet.
That's my favorite.
