To solve this problem, we can use the concept of permutations.
Since there are 7 flavors to choose from, the person has 7 options for the first (top) flavor, then 6 options for the second (middle) flavor, and finally 5 options for the third (bottom) flavor.
So, the total number of ways a person can order one ice cream cone with 3 different flavors of ice cream is 7 * 6 * 5 = 210 ways.
In how many ways can a person order one ice cream cone with 3 different flavors of ice cream if there are 7 flavors to choose from and it matters to the person how the flavors are stacked on the cone? That is, which flavor is on the top,middle,and bottom
