Find P(A∩B) for Dependent Events A and B
P(A)=0.2 , P(B)=0.09 , P(BgivenA)=0.03
Step 1
When A and B are dependent events, the probability of A and B occurring is P(AB)=P(A)(P(B|A)), which is called the multiplication rule for dependent events A and B.
P(AB)=P(A)(P(B|A))
Step 2
Fill in the known values.
P(AB)=0.20.03
Step 3
Multiply 0.2 by 0.03.
P(AB)=0.006
