The Large Counts Condition is satisfied when both np and n (1-p) are greater than or equal to 10, where n is the sample size and p is the probability of success. In other words, if the number of successes and failures in the sample is large enough, then we can assume that the distribution of the count of successes follows a normal distribution.

This is known as random variation. The p-value that is calculated in a statistical test reflects the likelihood that the observed difference between the variables occurred by chance.
