**Reiny**, Friday, December 6, 2013 at 6:43pmthe three circles can cut each other in 6 different points (think of a typical Venn diagram)

A line can cut a circle in 2 point

so each line can cut all the circles in 6 points

so total = 6 + 6 + 6 = 18

BUT, let's not forget that the two lines can also intersect

so the total is 19
