Show answer & explanation

Correct answer: D

Answer: 30 ways

Explanation:

  1. Find the number of ways to choose 2 flavors from 6 for one pizza type: use combinations because order does not matter. C(6,2) = 15.

  2. There are 2 pizza types and the two flavors chosen must be of the same type, so multiply the per-type count by 2: 2 × 15 = 30.

Final result: 30 ways.
