Suppose I flipped a coin \(n=3\) times and wanted to compute the probability of getting heads exactly \(X=2\) times. This can be done with a tree diagram. You can see that the tree diagram approach will not be viable for a large number of trials, say flipping a coin \(n=20\) times.. The binomial distribution is a probability model that …
