Vocabulary:Multiplication Principle of CountingIf you want to count all the outcomes from a sequence of tasks, count how many outcomes there are from each task and multiply those numbers together. More precisely, suppose the first task in a sequence has n1 outcomes; for each of these, the second task has n2 outcomes; for each of these, the third task has n3 outcomes; and so on. Then the number of possible combined outcomes from the whole sequence of tasks is n1 × n2 × n3 × … .

Addition Principle of CountingThe total number of outcomes among two tasks is the sum of the number of outcomes from each task ﴾minus the number of outcomes that are common to both tasks, if there are any﴿.
