Need help to solve calculus problem

A box contains 8 black and 10 white balls. One ball is drawn at random. What is the probability that the ball drawn is black?

Thanks

This problem is very simple. What have you learned about probability in class so far?
 
There is certainly no "Calculus" involved here, just basic arithmetic. And knowing the basic definitions, of course.
