When there are $4$ points on the circle, how many different triangles can be formed by connecting three points? A. $4$A. $4$ B. $8$ C. $24$ D. $64$ E. $12$
1. Because $3$ points must be chosen out of $4$ points on the circle and order does not matter, $\cfrac{{4}\times{3}\times{2}}{3\times{2}\times{1}}=4$ triangles can be formed. No More Steps
