To find the chance that A and B both occur, the multiplication rule multiplies P(B) by:
AP(A) plus P(B)
BP(A) minus P(B)
CP(B) squared
DP(A given B)
Answer & Solution
Correct answer: D. P(A given B)
1. First B happens, with its own probability.
2. Then A must happen in the world where B already did.
3. So multiply P(B) by the conditional probability P(A given B).
