Homework Statement
This problem was under applications of Bayes theorem, but I feel like I am bad at using it if that's the case:
At a school 30% of the students are girls. 4% of the girls are geeks and 2% of all geeks are girls. What is probability that a random student is a geek.
Homework Equations
Bayes theorem
The Attempt at a Solution
P(AlDI) = P(DlAI)/P(DlI) *P(AlI)
I guess I should assign the statement to A: a student is a geek
And as my data I don't know what to use. That 4% of girls are geeks?
Using Bayes theorem I found that 3/5 is the probability. Is this right and how do you arrive at it using Bayes theorem?
