Hi all
What is your answer to this one? 

In a school, 14% of students take drama and computers, and 67% take computer class. What is the probability that a student taking computers also takes drama?
     81%
      21%
      53%
      None of the above

I got that too.

If there are 100 people in the school, 14 take both, and 67 take computers all together. So that's 14/67.
