What is referred to as an 'event' in probability?

• The total number of outcomes

• The outcome of a die roll

• A specific result we are interested in

• Rolling a die

How do you calculate the probability of an event?

• Total outcomes minus favorable outcomes

• Possible outcomes divided by favorable outcomes

• Favorable outcomes plus possible outcomes

• Favorable outcomes divided by possible outcomes
