An ice cream store sells 27 flavors of ice cream. Determine the number of 6 dip sundaes.
xz_007 [3.2K]

Answer:

 \large\boxed{\large\boxed{2.428678219969\times 10^{15}}}

Explanation:

It is said that the <em>order is not considered</em>, meaning that the order does not matter. For instance, ABCDEF is equal to any combination of those same letters.

Thus, this problem deals with combinations, whose formula is:

          C(m,n)=\dfrac{m!}{n!\cdot (m-n)!}

For <em>27 flavors of ice cream</em> and <em>6 dip sundaes</em>, m = 27 and n = 6:

        C(27,6)=\dfrac{27!}{6!\cdot (27-6)!}=\dfrac{27!}{6!\cdot 13!}=2.428678219969\times 10^{15}
