General Addition Formula

  • P(AUB)= P(A) + P(B) - P(A∩B)

  • P(AUB, but not both)= P(A) + P(B)-2P(A∩B)

New cards

Conditional Probability

When we want to know the probability of an event after we know that another event has already happened

4
New cards

Conditional Probability Formula

P(B|A)= P(A∩B)/P(A)

5
New cards

Make sure you know which event is given for conditional probability because..

P(A|B) is NOT the same as P(B|A)

6
New cards

Independence formula

P(B|A)=P(B) (the probability that B happens is the same whether or not A happens)
