If all the outcomes are equally likely, how is probability of an event calculated?

• # of outcomes in the event divided by the total # of outcomes

• # of outcomes in the event# of outcomes in the event multiplied by the total # of outcomes

• the total # of outcomes divided by the # of outcomes in the event

• the total # of outcomes multiplied by the # of outcomes in the event

The addition rule for mutually exclusive events A and B says that

• P(A or B) = P(A) + P(B)

• P(A or B) = P(A) - P(B)

• P(A and B) = P(A) + P(B)

• P(A and B) = P(A) - P(B)
