For example, if we flip a fair coin N = 1000 times, the probability of getting exactly z = 500 heads is only 2.5%, even though z = 500 is precisely what we would expect if the coin were fair. Therefore, instead of determining the probability of getting exactly the result z/N from the null hypothesis, we determine the probability of getting z/N.

If this experiment is repeated, say 10 times, and the number of heads in each series of 3 tosses is counted, you will have a set of numbers like 0,1,3,1,2,2,1,1,3,0. The average of these numbers is the average value for the random variable, the number of heads in 3 tosses of a fair coin. That is because there is a 1% chance of picking the two-headed coin, which has a 100% of getting 10 heads, and a 99% of picking a fair coin, which has a (1/2) 10 chance of flipping 10 heads in a row This coin is tossed three times However, when it comes to practical application, there are two major competing categories of probability ....
