Hi!

What exactly is condition probability?

Whenever you see the word GIVEN you know it is a conditional probability.

The given part does not matter if events are independent.

But if the events are not independent then one event might affect another. This is conditional probability, Because we have a CONDITION that something has already happened.

To find a conditional probability, make whatever is the â€śgivenâ€ť your denominator. Then put what is asked for as your numerator. For exampleâ€¦ find the probability that we pick a woman, given that the person is between 40-49. This is labeled as P(Woman | 40-49), or â€śprobability of picking a woman, given she is between 40-49â€ť. Put ALL people 40-49 on the denominator, then all the women in that category on the numerator.
