For example, the theoretical probability that you will flip a coin four times and get heads each time is:
1/2 * 1/2 * 1/2 * 1/2 = 1/16, where probability of getting heads on a single coin flip = 1/2
In other words, if you attempt four coin flips sixteen times, you should IN THEORY get 4 consecutive heads one time.
If you actually conduct the experiment, you may get none, you may get five, who knows? You will only find out by DOING the experiment. As is often the case when you do, the experimental probability turns out to be higher than the theoretical probability.
This got me thinking about how we often will label things that we really, really want in our life as IMPOSSIBLE. Well, at least impossible for someone like me. Have you ever heard yourself say that something that you wanted to do or accomplish was impossible?
