On St. Patrick's Day, you took note of who was coming into your restaurant wearing green. What is the probability that someone was wearing green given that the customer is female?

The probability that someone is wearing green dress is a female is 0.25.

Step-by-step explanation:

First of all there are 2 probabilities. Wearing a green dress and not wearing a green dress.

Second of all if they are wearing green dress if it's male or female.

So the probability of wearing a green dress is 0.5

And its given that it is female. So,

0.5 (0.5) = 0.25

There is a 0.25 probability that the customer is a female wearing a green dress.
