What is probability and how does it helps?

Probability is the calculation of the extent to which something is probable (the likelihood of something happening or being the case). Probability helps staticians and other people to have a better understanding of what is to come in the future. Ex: If I have a bag of 10 colored marbles where five of them are blue and five of them are red, once I pull out a certain number of red and blue marbles I still know the ratio of red to blue marbles in the bag though it may have changed.
