If the probability an event will occur is p and the probability it will not occur is q, then each term in the expansion of (p + q)n represents a probability.The probability that a person in the general population suffers from anxiety is 0.25. If five people from the general population are randomly selected, the probability that three of them will suffer from anxiety is the third term of the binomial expansion of 
(0.25 + 0.75)5.
