I can explain you conditional probability with an example. I had explained you what is conditional probability problem earlier.
When for example an event B is related to event A. Event B which happened is that event that A has already occurred. Here below i have the formula to calculate conditional probability.
The formula to calculate conditional probability is P(B/A)= P(A and B)/ P(A)
The given event A has occurred; we should a reduced sample space. Instead of the entire sample space S, now we have a sample space of A since we know A has occurred. So the old thing is about being the number in the event divided by the number in the sample space still applies.
It is the number in A and B (should be in A since A has happened) divided by the number in A. By dividing on right hand side by the number which is present in the sample space S, and then we have the probability of A and B divided by the probability of A. Another important method of conditional probabilities is given by Bayes's formula.
A simple question how long is a decade answer me guys and i will get back to you.....
