Introducing probability


We know an event will occur, but how often will it occur? This is how we can quantify probability, and this is what we will use to control the frequency of an outcome. So, let's say we flip a quarter. The event we know will occur is heads (H), but it can still land on tails (T). So, the way we would write the probability of landing on heads is P (H) =?

At this point, we know that heads will occur, although we still don't know how often it will occur. To understand this, we must first get the number of possible outcomes that meet our conditions, which is 1 for heads. Then, we must get the number of events that are equally likely to occur, which is 2. So, now we need to put this in the equation for probability:

# of possible met conditions / # of equality likely outcomes

If we do some basic math and break it down further, we will have 50%:

P (H) = 1/2 = 50%

So what this says is, if you flipped a coin a million or even a billion times, the more the number of times you...
