How can the probability of an event a be expressed mathematically?

• p(a) = total number of possible outcomes / number of favorable outcomes

• p(a) = number of favorable outcomes - total number of possible outcomes

• p(a) = number of favorable outcomes / total number of possible outcomes

• p(a) = number of favorable outcomes + total number of possible outcomes
