thaaaanks!

Answer 3

Think about it reasonably; in a binomial distribution, we're considering Bernoulli trials, where we either have a success (with probability \(p\)) or we have a failure (with probability \(q\)). With only two options, it makes sense it's either one or the other. Ask yourself what the probability of having a success OR a failure. Since these two events are mutually exclusive, we know we always have one or the other, we know this is true 100% of the time, and thus we know the probability is \(1\).
