When there are $8$ points on the circle, how many different triangles can be formed by connecting three points? A. $56$A. $56$ B. $112$ C. $336$ D. $512$ E. $168$
1. Because $3$ points must be chosen out of $8$ points on the circle and order does not matter, $\cfrac{{8}\times{7}\times{6}}{3\times{2}\times{1}}=56$ triangles can be formed. No More Steps
