What are the differences between probability and coincidence?
Thank you for the opportunity to help you with your question!
Probability is mathematical term we use to describe the likelihood that something will or will not occur. For instance, if you have 3 blue marbles, 2 red marbles and 1 yellow marble in a bag, the PROBABILIY of choosing a blue marble on the first pick is 3/6 (3 blue marbles, 6 total marbles). Coincidence is what happens when (sometimes) the most unlikeliest things happen. For instance, in Las Vegas, there is a game where you guess what number will come on next on a wheel. The probability of each number being equal (statistically), yet if you look at the board of past number, it appears that certain numbers come up more times than others (I noticed this on a trip to Atlantic City and the entire office staff was allowed to go). Although it may appear that statistics lie in this instance, it is a coincidence (highly improbable, but possible) that certain numbers will be repeated several times. Statistics indicate that all things being equal (all numbers have an equal percentage of showing up), each number has the exact same chance of coming up. Previous numbers that are the same that come up are coincidence (in other words, highly unlikely statistically, but can happen). The fact that the same numbers keep appearing give betters the illusion that those numbers come up with much greater frequency that other numbers (false assumption).
