Homework Help: Math

Posted by Dan on Monday, June 24, 2013 at 1:02am.

A circle of radius 1 is drawn in the plane. Four non-overlapping circles each of radius 1, are drawn (externally) tangential to the original circle. An angle γ is chosen uniformly at random in the interval [0,2π). The probability that a half ray drawn from the centre of the original circle at an angle of γ intersects one of the other four circles can be expressed as ab, where a and b are coprime positive integers. What is the value of a+b?
