Question

One hot evening, Hulk was sipping tea at his home when he saw She-Nerd jumping around and wondered what was happening. Hulk suddenly remebered that his teacher once taught him Conditional probabilities with logs and couldn't remember anything about it anymore.
He ended up smashing up new computers but stll couldn't remember anything.
He was thinking what was Bayes' Rule and Conditional probabilities with logs?

Answer 1

Baye's rule:

if A1,A2,A3....An are mutually exclusive and exhausive events in a sample space(total events) and A is another event such that P(A) not eual to 0,
P(A/Aj)=P(Aj)P(A/Aj)
------------------
sigma j=1 to n,P(Aj)P(A/Aj)

conditional probability:
if A and B are two events in sample space and P(A)not equal to zero.the probability of B afetr the event A has occured is called conditionality probability of B given A is denoted by P(B/A)

P(B/A) = n(A intersection B)/n(A)
= P(A intersection B)/P(A)

hope this helps
