Frage Antworten
Diagram we will be using for reference :
P(R2|R1) = P(R2) is for when..... It's independent (does not depend on previous results)
If mutually exclusive, then.... A ∩ B = ∅ So P(A∩B)=0
What is P(R1∩R2) ? P(R1) x P(R2|R1) = P(R1) x P(R2) = 0.09
What is P(R1∪R2) ? P(R1) + P(R2) - P(R1∩R2) = 0.51
What is P(R1'∩R2') ? P(R1') x P(R2')
