a) In how many parts, we can divide an infinite plane by n straight lines of which no two lines  are parallel and no three lines are concurrent?

b) In how many parts, we can divide an infinite space by n  planes of which no four planes meets in a point and no two planes are parallel?

How to answer both these questions? What are the answers to these questions?

I am working on these questions.

Any math help, problem solving hint will be accepted.
