Question

Quizplus · Accepted Answer

The multiplication rule and addition rule are both used in probability calculations, and can be used together in some instances. For example, to calculate the probability of rolling a 3 on a fair die and then flipping tails on a fair coin, you would use the multiplication rule (probability of rolling a 3 and flipping tails) and the addition rule (probability of rolling a 3 and flipping heads, plus the probability of rolling a number other than 3 and flipping tails).
